Hi,

1. There is a PGM "PGM1" which write to an output file "OUT.FILE".

2. How can I check using JCL whether the file "OUT.FILE" is empty or not before executing the program ?

Thanks & Regards,

Ranjit Bhingare

Please use below JCL

//STEP01R EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//IN1 DD DSN=Give your input file,DISP=SHR
//OUT1 DD DUMMY,
// DCB=(RECFM=VB,LRECL=2356)
//SYSIN DD *
REPRO INFILE(IN1) OUTFILE(OUT1) COUNT(1)
/*
//*

Hello,

What will you do if there IS data in the file? Should PGM1 perform differently based on whether the file has data or is empty?

Do you want to write over any data already in the file?

Do you want to append new data to data already in the file?
