Paul,
I am not sure why DFSORT is dragged into this topic, but you don't have to
code dozens of DFSORT commands. I always believe in using the right
utility for the job. Scheduling jobs is not something DFSORT can process,
however it can handle simple requests. Here is a sample to submit a job
based on the day of the week. we can validate the date and time too.
//***************************************************************
//* GENERATE THE SUBMIT COMMAND BASED ON THE LOCAL DAY OF WEEK *
//***************************************************************
//STEP0100 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SYMNAMES DD *
DAYOFWEEK,S'&LWDAY'
MONJOB,'YOUR.JOB.PDS(JOB1)'
TUEJOB,'YOUR.JOB.PDS(JOB2)'
WEDJOB,'YOUR.JOB.PDS(JOB3)'
THUJOB,'YOUR.JOB.PDS(JOB4)'
FRIJOB,'YOUR.JOB.PDS(Job5)'
SATJOB,'YOUR.JOB.PDS(JOB6)'
SUNJOB,'YOUR.JOB.PDS(JOB7)'
//SORTIN DD *
A
//SORTOUT DD DSN=&&J,DISP=(,PASS),SPACE=(TRK,(1,1),RLSE)
//SYSIN DD *
OPTION COPY
INREC OVERLAY=(01:DAYOFWEEK,
10:1,3,CHANGE=(55,C'MON',MONJOB,C'TUE',TUEJOB,
C'WED',WEDJOB,C'THU',THUJOB,
C'FRI',FRIJOB,C'SAT',SATJOB,
C'SUN',SUNJOB))
OUTREC BUILD=(10,55,JFY=(SHIFT=LEFT,LEAD=C' SUBMIT ''',
TRAIL=C'''',LENGTH=80))
//*
//***************************************************************
//* SUBMIT THE JOB *
//***************************************************************
//STEP0200 EXEC PGM=IKJEFT01
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD DISP=(OLD,DELETE),DSN=&&J
