That will round out each CSECT to a 4K multiple. Suppose you want to
link two or more CSECTs together and have the resultant *module* rounded
to a 4K boundary?
I haven't tried this, so there's probably a flaw I've missed (or perhaps
I misunderstand what you want) but how about something like:
DRIVER1 CSECT
...
LTORG ,
DS 0D
DRIVER1L EQU *-DRIVER1
*
DRIVER2 CSECT
...
LTORG ,
DS 0D
DRIVER2L EQU *-DRIVER2
*
TOTAL EQU DRIVER1L+DRIVER2L
PAD EQU (((TOTAL+4095)/4096*4096-TOTAL)
*
DC (PAD)X'00'
