User-specific Variable in JCL

MVS Version 4.2 introduced the &SYSUID variable which should contain the userid associated with the batch job. This allows you, for instance, to allocate user-specific datasets: //REPORT JOB .... ,NOTIFY=&SYSUID //STEP1 EXEC PGM=USERINFO //SYSPRINT DD DISP=(,CATLG,DELETE),DSN=&SYSUID..USERINFO.LIST, // SPACE=(TRK,1),UNIT=SYSDA This program will allocate an output dataset userid.USERINFO.LIST. Note the use of &SYSUID in the NOTIFY parameter to notify the userid associated with the job.

The &SYSUID variable can also be used to allow user-specific values to be assigned to symbolic variables for a job:

//REPORT JOB .... ,NOTIFY=&SYSUID //RJCL JCLLIB ORDER=(&SYSUID..BATCH.PROFILE,APPL.JCL) //STEP1 EXEC REPORT The procedure REPORT could include the following JCL statement: // INCLUDE MEMBER=SETVAR which would include member SETVAR from either userid.BATCH.PROFILE or APPL.JCL, if the member didn't exist in the user's BATCH.PROFILE dataset. Member SETVAR could make use of JCL SET statements such as // SET REGION='ONTARIO',PRTDEST='CENTRAL',SORT='COUNTY' to assign values to symbolic variables that customize the procedure to a specific user's needs without giving each person their own version of the JCL procedures. Kind of an ISPF profile dataset for batch! A default SETVAR member in APPL.JCL could be used if there was no user-specific member.
