hi,guys,
when i use the follow jcl to create a GDG file.
| Code: |
//STP0100 EXEC PGM=IEFBR14,
// COND=(0,NE)
//DD1 DD DSN=AATP.AAIP.CLEP64.PS(+1),
// DISP=(,CATLG,DELETE),UNIT=SYSDA,
// SPACE=(CYL,(1,5),RLSE),
// DCB=(MODEL.DSCB1,BLKSIZE=27998,LRECL=4140,RECFM=VB)
|
but after the GDG generated, the Data class is **None**.
| Code: |
