Jcl variable substitution. JCL tailoring directives.

Jcl variable substitution In order to get the quoting right but still provide for substitution in the index portion of the variable name, a little help from subst is needed. These examples reflect names of substitution variables that might be present in user-defined JCL. Controlling the system where a JCL & VSAM: 0: Rexx Variable Substitution with POS c CLIST & REXX: 8: Using dynamic substitution in jcl on JCL & VSAM: 14: GDG substitution: JCL & VSAM: 7: Search our Forums: IBMMainframes. The VALUE keyword can contain a In the JCL VARIABLE TABLES panel, specify whether variables will be substituted during the setup of the job or when the job is submitted. JCL(PROGRDO). So the operator followed my IBM Workload Scheduler for z/OS imposes some restrictions on the values that variables can take and positions in the JCL where you can use variable substitution. A compound variable is made up of a concatenation of: The values of the percent variables making up a compound variable are not Use JCL substitution to add user or global variables to the JCL that is generated by Developer for z/OS®. If you have z/OS ® JCL variables within such procedures, their substitution is independent of any substitution made by HCL Workload Automation for Z. The possible causes follow, grouped by parameter type: Common causes: One or more parentheses missing. Instead, these values are used to form new variables, which have their When using a variable in a job, precede it with an ampersand (&), a percent sign (%), or a question mark (?). See Compound variables. MFBSIJCL may also automatically handle system parameters like DATE, DAY, When processing JCL from EQQJBLIB (not from the JS file) which includes: IBM Support . Instead, these values are used to form new variables, which have their own values assigned. If you do this, job To maintain compatibility with variable substitution within z/OS® JCL procedures, Tivoli Workload Scheduler for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in Table 21. But in dataset name, It has to followed by the dot sign after the variable name. The target variable, on which the dependency is related to, does not need to have been previously referenced in prior Workload Automation Programming Language statements. The field JSVVVALUE of the JSVV segment can be assigned a new value. The JCL Management Facility (JMF) is the most robust of the three facilities.

Google Analytics is used to store comments and ratings. Welcome to the HCL Workload Automation for Z documentation, where you can find information about how to install, maintain, and use the product. The Model JCL Substitution panel lets you replace symbolic variables with the actual values that are used in the JCL. You have to show what error you got. VARNVAL The value of the variable set by EQQJVXIT contains an assembler sample of the JCL-variable-substitution exit. If you are submitting a job contained in the job library, the exit is called at either job setup or job submission, but it is not called for promptable setup-variables. The VALUE keyword alone does not update any JCL variable table. Symbol The agent for z/OS uses special comment statements, called directives, to manage the inclusion and exclusion of lines and to control aspects of variable substitution. For system symbols within JCL, when the JCL undergoes conversion. z/OS V1R12. imposes some restrictions on the values that variables can take and positions in HCL Workload Automation for Z imposes some restrictions on the values that variables can take and positions in the JCL where you can use variable substitution. If you have z/OS® JCL variables within such procedures, their substitution is independent of any substitution made by Tivoli Workload Scheduler for z/OS. The exit can be called at either job setup or job submission, but is not called for promptable setup-variables. The original JCL is not changed. The JCL Substitution page is available on the Assembler, BMS, C/C++, COBOL, Link, When you create a variable using the JCL VARIABLE DEFINITION panel, you specify whether IBM Workload Scheduler for z/OS should substitute it at job setup, at job (or started task) Recall from Substitution Rule the method of integration by substitution. If you're not running a version of z/OS that supports in Use JCL substitution to add user or global variables to the JCL that is generated by Developer for z/OS®. This is called the phase of the substitution. Solve a system of equations by substitution. JCL with long PARM strings. Both CLIST and REXX versions are 2 MODIFY - Create a new JCL variable table or modify, copy, browse or delete existing variable tables 3 PRINT - Print variable tables See IWS manuals for more information . To provide a comment or rating for a topic, JCL & VSAM: The manual says: &JOBNAME The name of the job. . The following global variables are available: PDS Resolves to the partitioned data set to which the source member belongs. Restrictions on the use of variables Jump to main content Product Documentation In the JCL VARIABLE TABLES panel, specify whether variables will be substituted during the setup of the job or when the job is submitted. In this way, the actual values required for each command run are provided (for example, the occurrence name or Input Arrival date). . When you define a JCL or a job definition variable, you can specify the name of an exit that is called when substitution of the variable is required. Similarly, the variable &LHHMMSS. You can use a JMF variable as a substitution variable of a cataloged procedure. To update the JCL record, you must execute a SELECT JS request followed by an INSERT or REPLACE JS request. SCAN, SEARCH, TABLE In the template, surround each parameter in the JCL that must be substituted with exclamation marks (!), as shown in the following sample JCL. The %OWSID string is processed first.

When you define a JCL variable, you can specify the name of an exit that is called when substitution of the variable is required. You can create your own variables using the OPC JCL VARIABLE TABLES panel; these variables are stored in variable tables in the HCL Workload Automation for Z JCL variable substitution. The JCL Management Facility (JMF) feature allows you to change global variables and dates in JCL or Procs. vii FUWINDD: JCL substitution variable for input log file ddnames. The following sections of this document will describe the JCL Members in more detail. EQQJVXIT: Sample assembler JCL-variable-substitution exit. A compound variable is made up of a concatenation of: Does it know how to perform variable substitution if the variables are located in the data, as your example shows, instead of in the JCL? My gut feeling is that it wouldn't perform a variable substitution on data since that could easily cause a data integrity problem. Figures. You can specify the variable-substitution exit, rather than IBM Workload Scheduler for z/OS should substitute the variable. Variable substitution for job types with advanced options. Learn how to use Menu Manager to create a menu action for supplying values for the parameters that are Method 1: Using the SET and EXPORT in a JCL control statement: ALTER &TODAYDS - . This is called a simple variable. Nonpromptable setup variables are substituted. Prior to submitting a job to z/OS, PowerExchange resolves the defined substitution variables with the appropriate values. You can use a JMF variable as a substitution variable of a cataloged DELETE JCLV – JCL Variable Table Argument Name Description JCLVTAB JCL variable table ID. For more information, review the following chapter in: Control-M for z/OS User Guide JCL and AutoEdit Facility Variables overview & Global Variable Assignment and Syntax When parsing a JCL script, the parser simulates the JCL-variable substitution process performed by JES2.

Of course I can set MY OWN variables, as many as I want. PYK 2016-09-25: The general alternative to $ syntax for array variables is a bit tricky. These variables are resolved by the agent for z/OS in the JCL before the JCL is passed on to JES for execution. The examples will JCL substitution is mainly used when a repeatable process is used many times but needs the ability to behave differently based on variable information passed from the job that is executing 1) JCL variables are substituted into JCL statements during initial JCL parsing, along with resolving JCL procedures, etc. Using dynamic substitution in jcl on sql commands: IBM Mainframe Forums-> JCL & VSAM : Quick References View previous topic:: View next topic : Author The best suggestion I have is to use the JCL SET statement to define the variables, then pass them into a program via the PARM= statement and have your prgram write them out into a dataset Variable substitution does not take place within JCL procedures. At present its converting to upper case by default during execution. These variables are reserved, in the sense that Tivoli Workload Scheduler for z/OS will never try to read variable definitions for these variables from a variable table. Resources. OWSID is an operation-related supplied variable that is automatically set to the workstation ID for the current operation: assuming that FTW1 is the workstation ID, the first substitution step produces &FTW1SDIR. Next, create the JCL VARIABLE TABLE "JOBCARD" with the following two variables. Substitution parameters are variable names that take on a specified Learn how to identify and mark parameters for dynamic variable substitution. If start is negative (in other words, a minus sign appears before it), the system will count backwards from the ending position of the If JCL VARIABLE SUBSTITUTION is active, the first thing the CONTROLLER does when preparing to submit a job is to fetch the JCL VARIABLE TABLE and CALENDAR for that job so they can be used in resolving any OPC VARIABLES which may be in the JCL. (It would work just as well to add them to an existing table, so long at that table is associated with the application as described later). Instead, Workload Automation Programming Language automatically searches for JCL-variable-substitution exit. This JCL defines a program resource to CICS® that is in ELISEE. Overriding a DSN: I want to use the OPC variable (from OPC tables) in the JCL as a Variable. Controlling the system where a The Manager inserts the JCL parameter RESTART=<step> in the JOB card (if necessary) when submitting a JCL to the internal reader. PI05115: ABEND0C7 ON ISSUING JCLPREPA AGAINST JOB NOT IN CP WHEN JCL INCLUDES OPLSDATE VARIABLE &#160;&#160;&#160; TVAR&#160;&#160;&#160;&#160; =&#160; TVAR //* and then run the Variable Substitution Program then you get a S0C7 Variable substitution in z/OS® JCL procedures. The SET statement is a simple method that lets us use variables for substitution in a Mainframe batch job JCL. Variable substitution does not take place within JCL procedures. You can When you add global variables to the JCL Substitution page and then generate JCL or trigger a remote build or syntax check, a SET statement is generated just before the EXEC PROC statement. In the template, surround each parameter in the JCL that must be substituted with exclamation marks (!), as shown in the following sample JCL. MYCLASS. But please note setVariable only supports When freeing variable tables data areas, and resetting the pointer, it is checked if there is an additional reference to the same table, for which the pointers need to be reset as well. When an application program is running. Invocation parameters. FFECHUGF0 When a variable has been substituted with a value from the current variable table concatenation, that value remains valid for the entire substitution phase. Comments An example of the Command Variable (or Variable) column for substitution variables is shown in Examples of substitution variables. MESSAGE 55 IEFC620I UNIDENTIFIABLE CHARACTER " ON THE IF STATEMENT So there is no way I can check the contents of an alphabetical variable? Back to top: Robert Sample Global Moderator Joined: 06 Jun 2008 Posts: 8700 Location: Dubuque, After the job is over, you can check the variable in IOA ONLINE option IV VARIABLE DATABASE or reuse it in another batch job to see if it has been populated correctly. CA Driver is provided with CA WA The best suggestion I have is to use the JCL SET statement to define the variables, then pass them into a program via the PARM= statement and have your prgram With recent releases (2. For example IBM Workload Scheduler for z/OS imposes some restrictions on the values that variables can take and positions in the JCL where you can use variable substitution. IBM Tivoli Workload Scheduler for z/OS supports automatic substitution of variables during job setup and at job submit. VAR1 is a variable defined in a JCL variable table. If you want to avoid having IBM Workload Scheduler for z/OS scan the job for variables, you must set the VARSUB parameter on the OPCOPTS initialization statement to NO. the resolved substitution text for &JOBNAME is the name of the job assigned to the address space that calls the symbolic substitution service, not the address space of the started task. Before submitting a job to z/OS, PowerExchange resolves the defined substitution variables with the appropriate values. • JCL is reformatted automatically according to your specifications. For example, VARSET MYVAR VALUE(Hello World) causes any subsequent references to !MYVAR to be replaced with Hello World. SUBSTITUTION EXIT ===> _____ A load module name VALUE REQUIRED ===> Y Y - Yes, N - No DEFAULT POSITION ===> __ 01 - 80 A To add a user variable and parameter value for a JCL procedure that is used with a COBOL program, open the COBOL Settings page of the property group editor. These codes are used by the automatic job recovery function to Substituting variables. These codes are used by the automatic job recovery function to decide a Error codes. EQQJES3: JCL to assemble and link-edit a JES3 exit. 2) The same JCL variables are substituted into input data You can also specify substitution parameters to customise the JCL to a particular set of circumstances. The JCL Substitution page is available on the Assembler, BMS, C/C++, COBOL, Link, Fortunately you can just write SYMLIST=* to specify that all JCL variables are available. g, eval or subst ) but puts does not: it just prints the value out to its destination channel To maintain compatibility with variable substitution within z/OS® JCL procedures, Tivoli Workload Scheduler for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in Table 21. This is explained in a later section of this document. JCL preparation can be: SETUP=PROMPT A user must assign the value. Symbols that mark the end of variables. The name-value pairs given here are used to substitute global variables (as opposed to parameters, etc. Even if the z/OS JCL variable name is the same as an Tivoli Workload Scheduler for z/OS variable name, the values assigned to The JCL and control card templates DB2LDCTL, DB2LDCTP, DB2LDJCL, and DB2LDJCP include substitution variables. is replaced by the local date on which the job was started, and the date is in YYMMDD format. You must specify the defaults when calling PIF, otherwise no substitution takes place and the To maintain compatibility with variable substitution within z/OS® JCL procedures, Tivoli Workload Scheduler for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in Table 21. The first character in the original system symbol is position 1, the second is position 2, and so on. 1 I want to use lower case characters and underscore in SET variables in JCL. For each table, the command saves any variables flagged as SAVE(NO) and update the JCL Variable Table in IBM Workload Scheduler for z/OS. When running job JCL that contains a PROC (procedure) that uses symbolic substitution, not all variables are being substituted. Substitute the expression from HCL Workload Automation for Z imposes some restrictions on the values that variables can take and positions in the JCL where you can use variable substitution. JCL override with examples. You must replace properties specified with substitution values (that is, values enclosed in two plus signs, ++) with a suitable non-blank value before you submit the BFGCUSTM job. If you specify %FUWINDD as the ddname for the DD statement containing the FILE variable, then the resolved JCL contains ddnames appropriate to the system type and file type specified by the FILE variable: Table 1. These features only work with jobs submitted by Jobtrac. Still the same if set value is in quotes which it has to be when you have special characters like the & in it. , set escape \ update t set country = 'Trinidad and Tobago' where country = 'trinidad \& tobago'; Provided that you can set the variables ID and RUNNUM in your REXX, the FTINCL service will perform variable substitution for you. You must replace these substitution values with suitable values before you submit the BFGCUSTM job. A clearer way would be to turn on the Escape character and then escape the Ampersand. See IZWS configuration properties. EQQJES3U: JCL to install a JES3 exit as an SMP/E usermod. For more details about this exit, see Variable-substitution exit (on JCL or job definition variable). SCAN, SEARCH, TABLE Supplied variables. vii SEQQSAMP contains PIF samples for JCL variable substitution actions. Did you mean &WDAY? "// SET DATE=D&YYMMDD.

NEWNAME(&YESTDS) . You can specify, for example, whether the input will be numeric or alphabetic, or whether it should match a predefined picture. If the SubData generation option is set to Y, You appear to be confusing JCL symbolics with ISPF system variables. I could move line T1 down and run the JCL, then move line T2 down and run the JCL. g, eval or subst ) but puts does not: it just prints the value out to its destination channel 2 MODIFY - Create a new JCL variable table or modify, copy, browse or delete existing variable tables 3 PRINT - Print variable tables See IWS manuals for more information . It has the advantage that it treats the whole file as substitutable text, not just the JCL, so you can use it to tailor utility control cards as well, if this is required. Resolution This has been identified as a product issue, which has been addressed by defect/enhancement OCTCR50A389036. These codes are used by the automatic job recovery function to decide a When you add global variables to the JCL Substitution page and then generate JCL or trigger a remote build or syntax check, a SET statement is generated just before the EXEC PROC statement. HCL Workload Automation for Z supports automatic substitution of variables during job setup and at job submit. Zeke and OASIS variables can be used in both JCL and non-JCL statements submitted to the system by Zeke. "and "// SET If you have JCL substitutions that are done consistently for jobs to process correctly, look into using either CA Driver or global variables (or perhaps both). Generating the JCL programmatically and submitting via the internal reader was one approach considered. If the variable is preceded by a % and ended by a period or any termination character other than %, a value is assigned to the variable, and substitution, for this variable, completes. Symbol In the template, surround each parameter in the JCL that must be substituted with exclamation marks (!), as shown in the following sample JCL. For example, here is an implementation of a procedure that takes the name and index . The exit can be called at different IBM Workload Scheduler for z/OS can check input entered by the operator at job setup or by a substitution exit. EQQPIFJC is a sample 1) JCL variables are substituted into JCL statements during initial JCL parsing, along with resolving JCL procedures, etc. If you want to avoid having HCL Workload Automation for Z scan the job for variables, you must set the VARSUB parameter on the OPCOPTS initialization statement to NO. TEST. I tried the below one but the substitution is not working correctly. It is the responsibility of the user to verify that the steps exist in the JCL. These features also interface with JCLTRAC providing the correct JCL resolution and with each other. Contents. In this way, the actual The name can be any length. If you have z/OS® JCL variables within such procedures, their substitution is independent of any substitution made by IBM Workload Scheduler for z/OS. The parameter name for the ISPF and batch interfaces is VARTABLE. By leverage variable Having skimmed the variable substitution and INCLUDE parts (though the latter is close to non-existant) of some five out of maybe eight books in the TWS (formerly OPC) bookshelf, I recall the outer JCL to a JCL variable by means of a JCL SET statement and have it resolved that way in the included JCL statements. 5 Following is an example about how to set the variable values through a JCL, then save them to a UNIX properties file. You can perform JCL preparation through the program interface using resource type JS for JCL records, or JCLPREP for promptable variables. This section: Global variables and symbols always come in handy while standardizing your programs. Review the Documentation for this suite of To maintain compatibility with variable substitution within z/OS JCL procedures, the agent for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in the following table. This suite of programs is a mainframe JCL example that will describe how to define (or name) a variable value and then use or change the The contents of the string retrieved from the variable (or the command) substitution are not reinterpreted by the Tcl language core; they just get given to the command that you are calling. But JCL substitution is trying to catalog the file as MDMX017. a variable value and then use or change the variable Workload Automation Programming Language supports variable substitution within its control statements. VARSAVE [table-1,table-2,,table-n] You can specify as many tables as you want. 5 Workload Automation Programming Language supports variable substitution within its control statements. Restrictions on the use of variables. Substituting variables with embedded blanks. To maintain compatibility with variable substitution within z/OS ® JCL procedures, the agent for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in the following table. However, if the variables you create in Workload Automation Programming Language are also to be stored in the HCL Workload Automation for Z JCL Variable Tables, their names must also conform to the JCL Variable naming convention. HCL Workload Automation for Z also supplies several standard variables, which you can use in your job. 00 NOTE=> //*> UNDEFINED VARIABLE DS2 LINE 00005 OF ORIG JCL 000005 //DD DD System symbols and JCL symbols are character strings that represent variable information in JCL. My objective is, JCL variable should contain unix filenames and path. EQQPIFAP provides a PL/1 program to retrieve JCL and resolve all nonpromptable setup variables. VARTAB The name of the JCL-variable table. The JCL Substitution page is available on the Assembler , BMS , C/C++ , COBOL , Link , MFS , PL/I , Run , and ZUnit property group tabs. Also used for variable substitution in System Automation In the following example of a compound variable, two substitution steps are performed automatically. Compound variables. The contents of the string retrieved from the variable (or the command) substitution are not reinterpreted by the Tcl language core; they just get given to the command that you are calling. Controlling the system where a These variables are resolved by the agent for z/OS in the JCL before the JCL is passed on to JES for execution. Solve one of the equations for either variable. Symbol To maintain compatibility with variable substitution within z/OS ® JCL procedures, HCL Workload Automation for Z will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in Symbols that mark the end of variables. When you define a JCL variable, you can specify the name of an exit that is called when substitution of the variable is Jump to main content Product Documentation Customer Support; Workload Automation 9. They allow you to modify JCL statements in a job easily. Use the reformat function to change the JCL After we find the value of one variable, we will substitute that value into one of the original equations and solve for the other variable. IBM Tivoli Workload Scheduler for z/OS also supplies several standard variables, which you can use in your job. Controlling the system where a To maintain compatibility with variable substitution within z/OS ® JCL procedures, HCL Workload Automation for Z will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in Symbols that mark the end of variables. The VALUE keyword can contain a You can use substitution values, JCL variables, and configuration properties in the BFGCUSTM script. 1 You can use substitution values, JCL variables, and configuration properties in the BFGCUSTM script. 1 and 2. 1. The command that the value gets passed to might do its own thing with those characters, and those things might look a lot like substitution (e. You can use the resource type JCLPREPA rather than a combination of JS and JCLPREP requests. Using files to store the values won't be useful, because the values are derived from other variables as well (partly) during execution. By leverage variable substitution, you can set the value as what you want other than hard-coding. JCL tailoring directives. JCL/PROC override is useful when a proc parameters, data sets needs to be modified while executing it. ). Tivoli Workload Scheduler for z/OS supplies variables that you can use in your business. Incorrect variable name. 2) The same JCL variables are substituted into input data stream only at the moment the running program tries to open its DD * input data. The second JCL Member will delete the files created by the first JCL Member. The but can also be specified in a parameter file or as operating system environment variables. In case of job JCL Substitution Parameters JCL substitution is mainly used when a repeatable process is used many times but needs the ability to behave differently based on variable information passed from the job that is executing the process. com is not an official and/or affiliated with IBM I tried this and get the following (as expected). I can also use PARMSDD. Variable substitution in z/OS® JCL procedures. Permalink. An ampersand or percent variable can be assigned a value that is itself a variable. Controlling the system where a JCL variable substitution. The last definition of a variable wins. The JCL-variable-substitution exit is called at either job setup or job submission, when a JCL variable has retrieved its value. This panel is displayed when you enter the VER command from the MODIFYING A JCL VARIABLE panel (see You can perform JCL preparation through the program interface using resource type JS for JCL records, or JCLPREP for promptable variables. Therefore 2 MODIFY - Create a new JCL variable table or modify, copy, browse or delete existing variable tables 3 PRINT - Print variable tables See IWS manuals for more information . While set define off works, you run into the problem of not being able to use Substitution Variables in the same query as an Ampersand. Even if the z/OS JCL variable name is the same as an IBM Workload Scheduler for z/OS variable name, the values assigned to the two variables will be If you want the variable substituted, you use a different sort of quoting or you run the result through subst (which is defined to work over strings). Temporary variable names must begin with T. Program Directory. If start is positive, the system will count from the starting position to the end of the string. Adding parameters, Nullifying the existing parameters or Overriding the parameters of a PROC are the common overrides that can be done via a JOB. without having to code the SYSIN as instream data in the JCL to use HCL Workload Automation for Z variables: Learn how to use Menu Manager and the JCL substitution mechanism to submit JCL with dynamic variable substitution. For example: For system symbols within a parmlib member, when the parmlib member is processed. The following table describes the environment variables for the BFGSTDIN DD statement for the BFGCUSTM JCL script, in an MFT command PDSE library data set (in the [Variables] section). For static system symbols that the z/OS provides, you can define substitution texts in parmlib or accept the default substitution texts. When you select a variable from panel EQQJVVCL, you can make detailed modifications to it using this panel: Variable substitution in z/OS® JCL procedures. When a library in the TWSz EQQJBLIB concatenation takes a new extent while the CONTROLLER is active, and the JCL for a TWSz- scheduled job resides partially in the old extents and partially in the new extent, TWSz is unable to fetch the JCL for that job. Resolution of JCL substitution variables. VARLGTH The required length of the variable value or X'00' if a length is not defined for the variable. imposes some restrictions on the values that variables can take and positions in If the VARSUB keyword of the OPCOPTS statement is set to SCAN, this directive, when found in the JCL of a computer workstation operation, informs HCL Workload Automation for Z that variable substitution should start from this line. 2), you have the option to use SET (i. You can create your own variables using the OPC JCL VARIABLE TABLES panel; these variables are stored in variable tables in the IBM Tivoli Contents. The program can be called as a CLIST, REXX exec, or ISPF edit macro. The JCL-imbed and automatic-recovery exits are called via IBM Workload Scheduler for z/OS JCL statements. The JCL member submitted to MFBSIJCL may contain parameters that are substituted before submission to Server Enterprise Edition / MSS. In this way, the actual values required for each command run IEFC653I SUBSTITUTION JCL - DSN=&&SORTOUT,UNIT=SYSALLDA,SPACE=(CYL,(1,1)),DCB=(LRECL=49) echoes the original record in the JCL member that contains Control-M AutoEdit Variables or IOA Global AutoEdit Variables. Some commands do reinterpretation of their arguments (e. Finally, we check our solution and make sure it makes both equations true. JMF can be used to insert JCL substitution by a date range, or it can be used to substitute any JCL statements or SYSIN data. Comments When you define a JCL or a job definition variable, you can specify the name of an exit that is called when substitution of the variable is required. Dependent variables work slightly differently from how they work with IBM Workload Scheduler for z/OS JCL Tailoring. 000002 // NOTIFY=XCALLIN,MSGCLASS=Q,CLASS=B 000003 //STEP001 EXEC PGM=IEFBR14 000004 //DD DD DSN=&DS1. When processing JCL from EQQJBLIB (not from the JS file) which includes: IBM Support . The preference, of course, is to just have a PROC that has a variable that could be populated by a program and picked up in the JCL as a substitution. The scheduler assigns error codes to certain operations and to job and started task steps. The JMF variable is resolved before the JES expansion of IEFC653I SUBSTITUTION JCL - OLD EQ "ORD" 56 // CLASE='A4_' 57 //IFPREG ENDIF STMT NO. If you have multiple programs of the same type, for example, COBOL with CICS® and Db2®, and these programs use the same JCL to compile and link-edit them, you can create an action that compiles each program by using the same JCL. Thanks to Morag who pointed me to the MQGEM blog post. Variable-substitution exit (on JCL or job definition variable) When you define a JCL or a job definition variable, you can specify the name of an exit that is called when substitution of the variable is required. Arithmetic expression with supplied date or time variables: A Submit variables are substituted. You can clearly see in the substitution JCL that no date value is being passed. I have the variable FECHUGF0 value as 1010 in table CSOLOTABLE. cmd string. Shown in 1-8 characters. Job scheduling and WLM. Both CLIST and REXX versions are included in the sample. The values of the percent variables making up a compound variable are not substituted directly. (Optional) IZWS can simulate the IZWS variable substitution based on a future To maintain compatibility with variable substitution within z/OS JCL procedures, the agent for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in the following table. For safety precautions I will recommend you to use EXPORT in the beginning of your JCL, because then you are sure that inline substitution works for all the JCL variables you might define in The scheduler assigns error codes to certain operations and to job and started task steps. Replace variable with its value This method applies to most variables. 202Y 302Y 502Y EQQJHDAN EQQJHJCT Temporary fix. The following table describes the mandatory MFT configuration properties for the BFGSTDIN DD statement for the BFGCUSTM JCL script in an MFT command PDSE library data set. This panel appears when there are user-defined symbolics in the model JCL or when you enter You can perform JCL preparation through the program interface using resource type JS for JCL records, or JCLPREP for promptable variables. Even if the z/OS ® JCL variable name is the same as an HCL Workload Automation for Z variable name, the values assigned to the two variables will be To enable JCL parameters substitution, add this setting to the mfbsi. PURGEMA. In the case above, a few more characters can be gleaned for resolution of the OETEVNM variable by changing the name of temporary variable TVAR1 to T1. SmartJCL –An introduction to IWS variables 10 • Directives to manage variable substitution, e. HCL Workload Automation for Z. BS100. 00 NOTE=> //*> UNDEFINED VARIABLE DS2 LINE 00005 OF ORIG JCL 000005 //DD DD The JCL templates DB2LDJCL, and DB2LDJCP include substitution variables. The examples illustrate the following guidelines and characteristics for entries in the Command Variable column: In JCL, normally Symbolic parameters is created using & (Ampersand sign) followed by the variable name. The exit can be called at different Variable substitution in z/OS® JCL procedures. SCAN, SEARCH, TABLE The agent for z/OS uses special comment statements, called directives, to manage the inclusion and exclusion of lines and to control aspects of variable substitution. None of these exits is JCL variable substitution. The variables are split into four groups: Occurrence-related variables To enable JCL parameters substitution, add this setting to the mfbsi. However, variable names may be reused within a single JCL member as is documented in the TWSz MANAGING THE WORKLOAD manual. It was prepared to mark where the substitution parameters are located. The variable &LYYMMDD. SEQQSAMP contains PIF samples for JCL variable substitution actions. Using JCL substitution, you can form compound variables. JCL tailoring directives Tivoli Workload Automation, Version 9. TVAR is a substring of VAR1 value, starting from position 2 for a length of 4 characters. Dynamic Workload Console Readmes. Jcl variable substitution for SYSIN (too old to reply) johann woeckinger 2019-01-24 13:18:10 UTC. Configuring the agent to run variable substitution To be able to run this type of variable substitution, you must configure some keywords of the TWSOPTS statement. Use command EJCK REPORTS to produce a full JCLCheck listing in order to view the resolved variables. k Thu Feb 28, 2008 9:46 am Getting Input Variable by fuuss » Wed Dec 10, 2008 8:20 am 5 Replies 2348 Views Last post by fuuss Fri Dec 12, 2008 10:35 am SET a variable with a file name, HELP by javivi » Thu Jan 27, 2011 9:01 am The JCL Management Facility (JMF) feature allows you to change global variables and dates in JCL or Procs. Jump to main content Product Documentation. For safety precautions I will recommend you to use EXPORT in the beginning of your JCL, The purpose of this example is to show how to use ZOS (or MVS) JCL and Procedures (or PROC's) with substitution parameters and overrides (or PROC override). I'd recommend that you move your variables out into the JCL (as specified The DSN and DISP used by the PROC's will be defined in the JCL Member and passed to the PROC via substitution or an override. In Tcl, the {} syntax technically means “do no substitutions at all on this”. It will not be changed when a different table is declared by a subsequent SEARCH or TABLE directive (see JCL tailoring directives), even if the same variable name is found later. SETUP=YES When returned, the data area parameter locates a JCL setup variable record, the header, a common segment, and a sequence of variable segments JSVV. ; In the left pane of the window, select JCL Substitution. When evaluating an integral such as \[\int_2^3 x(x^2 - 4)^5 dx, \nonumber \] Changing variables in SEQQSAMP contains PIF samples for JCL variable substitution actions. The following table describes these variables: JCL to install the JES2 EXIT7 as an SMP/E usermod. This record is replaced by the JCL statement appearing in the next record, For additional flexibility substitution parameters may be used to pass different values to a PROC. e. Promptable setup variables are substituted using the default values. Customer Support HCLSoftware U Community Forums Workload Automation Programming Language supports variable substitution within its control statements. When freeing a variables table area, all the references to that area in the TUB are reset as well. is replaced by the local time in which the job was started, and the time is in HHMMSS format. JCL tailoring directives The agent for z/OS uses special comment statements, called directives , to manage the inclusion and exclusion of EQQJVXIT contains an assembler sample of the JCL-variable-substitution exit. EQQPIFJC is a sample Use the VARSAVE command to save all the variables that are assigned to the tables specified. MESSAGE 55 IEFC620I UNIDENTIFIABLE CHARACTER " ON THE IF STATEMENT So there is no way I can check the contents of an alphabetical variable? Back to top: Robert Sample Global Moderator Joined: 06 Jun 2008 Posts: 8700 Location: Dubuque, The name can be any length. SYNTAX - Do syntax checking of JCL => Y RUNTIME - Do runtime checking of JCL => Y REMOTE - Do remote validation of JCL => N CHANGE - Do pre-validation variable substitution => Y - Substitute JCL, control cards, or both (JCL/CTL/BOTH) => BOTH Change file option (B-browse, E-edit, blank) => 000001 //XCALLINN JOB (885002,J09),'BOC',MSGLEVEL=(1,1). Example: //J&USER JOB 1 //MYSTEP EXEC PGM=MYPROG //MYDATA DD DSN=&USER. • User invokes the function out of the ISPF editor with a simple line command. \my. COOL Why is that so? I am afraid of inconsistency later, so I ask JCL Parameter Substitution. Explore how to Define and Use Variables with JCL. You can create your own variables using the OPC JCL VARIABLE TABLES panel; these variables are stored in variable tables in the HCL Workload Automation for Z The following keywords are optional: VALUE(value) Sets the value of the variable within Workload Automation Programming Language. v Tables. You can delete, copy, create, and modify JCL variable tables using this program. You can also use JCLPREPA to simulate variable substitution. A compound variable is made up of a concatenation of: The values of the percent variables making up a compound variable are not substituted directly. e. You must replace all variables that are specified with substitution values (that is, values enclosed in two plus signs, ++) with suitable values before you Following is an example about how to set the variable values through a JCL, then save them to a UNIX properties file. Controlling the system where a Fortunately you can just write SYMLIST=* to specify that all JCL variables are available. g. When all promptable variables of the JCL record are assigned, SELECT JCLPREP receives a return code 4. The parameter name for the z/OS UNIX interface is -W. During JCL variable substitution, incorrect syntax was found in SETVAR directive. ; Click Add User Variable. The EJCK command works as designed. The symbol preceding the variable determines how IBM Workload Using JCL substitution, you can form compound variables. EQQJVXIT contains an assembler sample of the JCL-variable-substitution exit. To update multiple variables in the same table, Percent variables can be used to form compound variables and simple variables. JCL variable substitution. The properties file contains variables and values that are used by subsequent steps. EQQJES2V: JCL to install the JES2 EXIT51 as an SMP/E usermod. SmartJCL –Product Presentation 10 JCL Reformat • Administrator specifies positions of keyword, value and continuation line indiviually for each JCL parameter according to your company needs. The table name can be 1–16 chars. Symbol start The character position where the substring is to start. How Transaction Analysis Workbench resolves a JCL substitution variable depends on the variable and, in some cases, the context in which the variable is used. System symbols can only be used in started task JCL To maintain compatibility with variable substitution within z/OS JCL procedures, the agent for z/OS will assume that a variable has ended (even if the completing period is missing) if the variable is followed by one of the symbols listed in the following table. In case of job Variable substitution does not take place within JCL procedures. The IZWS variable table must be passed when the JCL Expert client is invoked. Table 1 .
