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)
