Hi!
I want to execute a step only if a particular data set is empty. Can anybody help me to identify empty data set within JCL or guide to do this?
Thanks and Regards

You can try this:
Code: Select all
//STEP01 EXEC PGM=ICETOOL
//IN DD DSN=...your.file,DISP=SHR
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//TOOLIN DD DATA
COUNT FROM(IN) EMPTY
/*
//*
// IF (STEP01.RC) = 0 THEN
//STEP02 EXEC PGM=whennotempty
// ELSE
//STEP03 EXEC PGM=whenempty
//*
If you want to use IDCAMS for STEP01, you can use any of these:
Code: Select all
//INDD DD DSN=...file.to.be.checked,DISP=SHR
//OUTDD DD DSN=OUTPUT FILE,DISP=SHR
//SYSIN DD *
REPRO INFILE(INDD) OUTFILE(OUTDD) COUNT(1)
/*
If the file is EMPTY, you'll get RC=04.
You can also use:
Code: Select all
//STEP0001 EXEC PGM=IDCAMS
//IN DD DSN=...file.to.be.checked, DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSIN DD DATA
PRINT INFILE(IN) COUNT(1)
/*
If the file has a record it'll get RC=0 otherwise RC=4.
