;
|
|
; <3> 6/10/92 JSM CanÕt do a beqOld in DSEdit, since it isnÕt inside a patch proc.
|
|
; Just do the same thing the ROM does: repush the parameters and
|
|
; call _TEKey again. This means we donÕt need to include
|
|
; LinkedPatchMacros.a anymore.
|
|
; <2> 6/10/92 JSM Moved some routines here from DialogMgrPatches.a to factor out
|
|
; common code in both the ROM and the System. DonÕt define
|
|
; kProcessInfoRecSize here (it was 6 bytes too big anyway), use
|
|
; ProcessInfoRec.size from Processes.a. Implement DSEdit slightly
|
|
; differently for ROM builds and System builds.
