6/10/92 djw Add new selector for doSecondaryInit (a private routine) ;

6/10/92 djw Add new private trap macro's for AddCard, RemoveCard, ; and CheckSlot. ; 5/17/92 kc Add get sGetSRTEntry vector number. ; <5> 1/7/92 RB Added a couple of records structures used to identify faulty ; drivers in Apple display cards. ; <4> 1/30/91 gbm sab, #38: Change the Ôalready including this fileÕ variable to ; all uppercase (for security reasons) ; <2> 1/17/90 djw Add new slotmgr private selector GetBoard ; <1.9> 6/30/89 djw removed pSlotStatus. ; <1.8> 4/16/89 GGD Added new data structures used by SlotInterrupts.a and ; VerticalRetraceMgr.a ; <1.7> 4/12/89 djw Removed including slotequ.a and duplicate state constants ; (state_sdminit,...) ; <1.6> 3/28/89 djw added an SRT entries count to globals. Added macros for private ; routines, added last SRT ptr in globals. ; <1.5> 3/12/89 djw changed srt link block and added some mark values, deleted ; SRTlastBlk ptr in globals and substituted expansion chassis ; support fields. ; <1.4> 3/1/89 djw change srrblock flag field from byte to long ; <1.3> 2/20/89 djw added SRT header record definition, added slot mgr globals ; record. added flag field to srrBlock for enable/disable. ; <1.2> 1/6/89 djw Add slotVNum for slot version number ; <1.1> 11/17/88 CCH Added stuff from system build. ; <1.0> 11/9/88 CCH Adding to EASE. ; <1.0> 10/24/88 djw Adding for the first time into EASE. ; 1/10/88 djw created - removed sSDMRecord and state equates ; ;_______________________________________________________________________________________ IF &TYPE('__INCLUDINGSLOTMGREQU__') = 'UNDEFINED' THEN __INCLUDINGSLOTMGREQU__ SET 1 Include 'Slots.a' ;--------------------------------------------------------------------- ;MACRO: sNextStep(VAR Step:Dx; VAR Temp:Dy; VAR sPointer:An) ; sNextStep creates a new pointer from the given pointer and step ; register.
