Yes, we can handle empty file in JCL, there is utility
provided by IBM "UT939" ,eg //STEP1 EXEC PGM=UT939,
IF step1 return code is 4 then there is empty file and else
if return code is 0 (for non-empty file). We can handle
this with COND parameters whether to execute next step or
not if file is empty.
SUPPOSE WE DON'T WANT TO EXECUTE THEN
eg //STEP2 EXEC PGM=XXX,
COND=(4,EQ,STEP1)

Read first record of the file using IDCAMS, It will return
the cc=0 if the file is not empty, otherwise it returns
CC=4.

The disp in the JCL is MOD and the program opens the file in OUTPUT mode. What happens ? The DISP in the JCL is SHR and the program opens the file in EXTEND mode. What happens ?

Hi, Say I have 10 flat files and I want to copy all these 10 flat files to a GDG versions flat files (I have GDG base: FDWS01.TEST.RESTORE) in one shot. Can we do that in one shot using a JCL. May be by using IEBGENER. It's a bit urgent. So anyone's fast rely would be appreciated.. Thanks in advance.. 10 flat files ----------------------------------- FDWS01.SUB.RESTORE1 FDWS01.SUB.RESTORE2 FDWS01.SUB.RESTORE3 ; ; FDWS01.SUB.RESTORE10 TO GDG versions ----------------------- FDWS01.TEST.RESTORE.G0001V00 FDWS01.TEST.RESTORE.G0002V00 FDWS01.TEST.RESTORE.G0003V00 ; ; FDWS01.TEST.RESTORE.G0010V00
