After step1,before step2 , create another step , say stepA.
in step a , cheCk for the file in step1 is empty or not
using the IDCAMS utility
//STEP1 EXEC PGM=PG1
//DD1 DD DSN=TPAR.T01.A,DISP=(NEW,CATLG,DELETE),
DCB=(RECFM=FB,LRECL=80,BLKSIZE=800),
SPACE=(TRK,(5,5),RLSE),UNIT=PROD
//STEPA EXEC PGM=IDCAMS
//DD2 DD DSN=TPAR.T01.A,DISP=SHR
//SYNID DD *
PRINT INFILE(DD2) COUNT (1)
END
//IF (RC.STEPA = 4) THEN
//STEP2 EXEC PGM=REPORT
//DD3 DD DSN = XXX.XX.XX
//ELSE
//STEP3 EXEC PGM=PGM2
//ENDIF
if the file is empty , stepa will return 0 else it
reuns 4. If your file consists of the header and trailer
give count(3).
