Hi,

Try these 2 links:

P.S. Try using the SEARCH Facility before you post.

Hi,
You can do this by using cond parameter. Introduce a IDCAM step to check the file, if it empty then idcam step will return 4. Based on that you can bypass your step no 3.
//STEP01 EXEC PGM=IDCAMS,COND=(0,NE)
//SYSPRINT DD SYSOUT=*
//FILE1 DD DSN=TEST.DATA,DISP=SHR
//SYSUDUMP DD SYSOUT=*
//SYSIN DD *
PRINT INFILE(FILE1) -
DUMP COUNT(1)
/*
//* DON'T RUN STEP02 IF FILE IS EMPTY
//* A RETURN CODE OF 4 WOULD INDICATE NO RECORDS WERE FOUND
//STEP02 EXEC PGM=WHATEVER,COND=(4,EQ,STEP01)

Thanks

Hi subhasis_50,
Not taking into consideration of COND parameter, first of all how do we know whether the file is empty or not in jcl
