20 year amateur assembler programmer here.
Sometimes I see macro expansions (and just open code) with code like the
following.
L 12,X'14'(,12)
AH 12,AFLENG-DFHAFCB(,12)
L 12,AFPFXLEN+AFTKTCB-AFTSTART(,12)
LLGT 12,UKTCB_ACTIVE_TASK-DFHUKTCB(,12)
LLGT 12,UTATCAA-DFHUTASN(,12)
Is that code equal to this?
L 12,X'14'(,12)
USING DFHAFCB,12
AH 12,AFLENG
USING AFTSTART,12
L 12,AFPFXLEN+AFTKTCB
USING DFHUKTCB
LLGT 12,UKTCB_ACTIVE_TASK
USING DFHUTASN
LLGT 12,UTATCAA(,12)
What is the "name" of this usage?
