|
|
; Change History (most recent first):
|
|
;
|
|
; <3> 7/17/90 dba got rid of most routines, since Memory.h now has in-line
|
|
; register-based interfaces; got rid of MemUtils.h because this is
|
|
; all compatible with the prototypes in Memory.h; replaced special
|
|
; code here with code excerpted from Interface.o source; it would
|
|
; be even better to use Interface.o and use dead-code stripping
|
|
; <2> 7/7/90 dba change names to match Interface.o
|
|
; <1.2> 3/3/89 CCH Added SetHandleSize and HUnlock glue.
|
|
; <1.1> 11/10/88 CCH Fixed Header.
|
|
; <1.0> 11/9/88 CCH Adding to EASE.
|
|
; <•1.3> 9/23/88 CCH Got rid of inc.sum.d and empty nFiles
|
|
; <1.2> 5/23/88 BBM Glue broken for three routines (ie. no rts)
|
|
; <1.1> 5/19/88 BBM Added more glue for memory manager, OS utils.
|
|
; <1.0> 3/22/88 EMT First time adding Notification Manager sources
