|
; Change History (most recent first):
|
|
;
|
|
; <16> 7/24/92 DTY #1034303 <gbm>: The Menu Manager calls the 'MDEF' with the
|
|
; CallMDEF utility routine. This routine locks the 'MDEF', calls
|
|
; it, unlocks it upon return, and returns to the caller.
|
|
; CalcMenuSize is an example of such a routine. The problem is
|
|
; that the 'MDEF' calls CalcMenuSize itself, which causes the
|
|
; 'MDEF' to get unlocked while itÕs still executing. If the 'MDEF'
|
|
; handle get relocated by the Memory Manager, youÕll crash.
|
|
; Bracket calls to CalcMenuSize with code that saves and restores
|
|
; the 'MDEF' handle state.
|
|
; <15> 5/14/92 KSM #1028474,<DCC>: Update patch that calls SCUpperText to skip the
|
|
; call when character is a one-byte null character for speed. Add
|
|
; patch to DrawMenuBar to synchronize the Keyboard menu (new
|
|
; KeyScript verb).
|
|
; <14> 1/22/92 JSM Add comment to PatchInsMenuItem to never roll this patch into
|
|
; ROM.
|
|
; <13> 10/10/91 PKE #1012672, For Cube-E (and Bruges): Use new SCUpperText routine
|
|
; in MenuKey instead of UpperText, so we are independent of any
|
|
; grafPort font. Include ScriptPriv.a.
|
|
; <12> 8/30/91 DTY Define hasCQD here since itÕs no longer defined in BBSStartup.
|
|
; Defining it to be 0 for the System build seems like the wrong
|
|
; thing since some of these patches apply to the colour machines,
|
|
; but thatÕs the way it used to be, so thatÕs the way itÕll stay.
|
|
; <11> 8/22/91 KSM csd,#Bruges: New InsrtResMenu call to fix sorting problem with
|
|
; FONTs & FONDs. Call _UpperText instead of _UprString, MARKS in
|
|
; MenuKey.
|
|
; <10> 7/10/91 dba end of the forPost70 conditional; we are post-7.0 for good
|
|
; <9> 3/31/91 dba gbm: load the new version of DisposeMenu on the II, IIci, and
|
|
; Portable as well, since they all need the bug fix to handle
|
|
; purged menus; also implement MenuChoice on the Plus, SE, and
|
|
; Portable (but only post-7.0)
|
|
; <8> 12/14/90 bbm (djw) roll in linked comefrompatch from patchIIrom.a.
|
|
; <7> 12/14/90 KSM <rlc>Fix bug in MenuKey (II,IIci,&Portable) where it is BTSTing
|
|
; a register for each item, but when the item is greater than 31,
|
|
; the BTST instruction wraps and we get flags for previous items.
|
|
; <6> 9/28/90 KSM <dba> Guarantee A5 world for calls into MDEFs.
|
|
; <5> 9/15/90 KSM Patch InsMenuItem to fix a PixelPaint bug!!*!
|
|
; <4> 7/26/90 KSM use GetMenuBar on the Macintosh II as well
|
|
; <3> 7/23/90 dba convert this into a linked patch
|
|
; <2> 12/19/89 EMT Removed references to routines that haven't been altered. Use
|
|
; PatchMacros.a.
|
|
; <1.3> 8/28/89 SES Removed references to nFiles.
|
|
; <1.2> 6/2/89 KSM Remove tear off menu support in this file. See MenuMgr_Patch.a
|
|
; <1.1> 6/1/89 KSM Added MenuDispatch for BigBang.
|
|
; <1.0> 11/16/88 CCH Added to EASE.
|

|
|
|
|
;
|
|
; <12> When hasCQD was defined in {AvailableFeatures} in BBSStartup, it was defined
|
|
; to be 0 for System builds, so keep it that way for future System builds. This
