|
|
; Function: This routine patches the PACKage dispatching in ROM. The reason this

; is done is that the ROM dispatcher will call _SysErr (can you say bomb)
|
|
; if the PACKage can not be loaded. This is punishment far in excess
|
|
; of the crime. Since all PACK=14 routines now have a return value and
|
|
; D0 specifies the amount of parameters on the stack, it is possible
|
|
; to remove the parameters and return gracefully with an OSErr.
