;
; Change History (most recent first):
;
; <SM5> 11/12/92 PN Get rid of ³ 020 conditionals for ROM builds
; <SM4> 11/6/92 SWC Changed PackMacs.a->Packages.a.
; <15> 6/12/92 FM remove MacsBug symbols and obsolete smgrKeepMacsBugSymbols
; conditional. Replaced long divisions w/ a macro that uses a
; divu.l instruction for 020 cpus and a subroutine otherwise.
; Removed if 0 then code from division routine.
; <14> 4/30/92 FM Remove conditional smgrUsesStdExit
; <13> 3/16/92 csd #1017570,<gbm>:
; Removed the MoveHHi call on the itl0 and itl1 resources to avoid
; System heap fragmentation.
; <12> 2/19/91 PKE smb,#DTS FT: ToggleDate trashes one word past the end of its
; ÒVAR lSecs: LongDateTimeÓ parameter (reported by a developer).
; <11> 2/15/91 PKE JSM,#54736: Redo conditionals to move change <10> to Post 7.0.
; Object compare identical to <9>.
; <10> 1/28/91 JH PKE,#54736: Changed InitDateCache so that the date separators
; are now part of the cache. Then fixed String2Date to use these
; separators and not be quite so forgiving about allowed
; separators. Now if a separator is used that is not part of the
; cache before a number is found the routine returns invalid date.
; If a non-cached separator is found after a number the routine
; continues, but a warning result is returned. Also changed
; ValidLong so that it won't allow numbers > 32768.
; <9> 9/14/90 BG Removed <8>. 040s are now behaving more reliably.
; <8> 7/17/90 BG Added EclipseNOPs for flakey 040s.
; <7> 7/5/90 PKE NEEDED FOR SIXPACK: Rearranged InitDateCache to fix old problem:
; itl0 and itl1 may be purged before we try to use them.
; <6> 6/1/90 PKE Just cleaned up some comments, formatting, and superfluous
; definitions.
; <5> 5/5/90 PKE Updated 3 previously overlooked ÔSysVersÕ symbols to
; ((smgrSysVers >= $605) OR (smgrROMVers >= 2)) so we can build
; with new ScriptPriv.a.
; <4> 4/10/90 PKE Deleted conditionalized definitions of forRom, SysVers and
; TestScriptManager. Fixed tabs. Replaced local definition of
; _FixDiv with include of FixMath.a. Used smgrSysVers,
; smgrROMVers, and smgrUseStdExit symbols instead of SysVers and
; buildLevel. Removed remaining MacsBug symbols for 7.0.
; <3> 3/4/90 PKE Changed _UprText to _UpperText to match new Traps.a.
; <2> 2/22/90 PKE Replaced obsolete _LwrStringToUpr opword with _UprText. Updated
; header to BBS format.
; <1> 12/18/89 CCH Adding for the first time into BBS. Changed include 'inc.sum.a'
; to load 'StandardEqu.d'. Updated file name references.
;
; (BBS versions above, EASE versions below:)
; <2.5> 11/6/89 PKE NEEDED FOR 6.0.5!! (since 2.4 change is conditionalized for 7.0,
; the file can be used as is, except that you might need to add
; back the load 'nEqu.d') -Bug fixes for InitDateCache and
; String2Date needed for HyperCard. InitDateCache: Fixed CopyArray
; to use correct register (A4) for source pointer, and to
; initialize all relevant bytes of length register (D0).
; String2Date: if first relevant (i.e., day or month name) alpha
; token is a month name, we now search the day name list if we
; find another alpha token (fixes BRC #54946). Rearranged Cache
; structure to fix invalid use of month/day name index. Note that
; the invalid index use in String2Date happened to work before
; because of the incorrect source pointer use in CopyArray, but it
; was incomprehensible.
; <2.4> 9/18/89 PKE Replace _GetScript call in InitDateCache with direct access to
; ScriptRecord, since we may not have GetScript yet; this is also
; an optimization.
; <2.3> 8/26/89 PKE Cleaned up some conditionals, moved a comment.
; <2.2> 8/22/89 SES Removed references to nFiles.
; <2.1> 6/30/89 PKE NEEDED FOR AURORA: Use OPWORD _LwrStringToUpr for LwrString with
; uppercase function; use _LwrStringToUpr instead of UprString in
; ToggleDate (ToggleDate may now move memory, but the 2.0
; documentation didn't indicate whether or not it moved memory).
; For ROMs on 020 or greater machines, get rid of LongDiv and move
; divs.l inline. Use constant NoonHr for 12 where appropriate.
; (all of these changes from code review).
; <2.0> 6/23/89 PKE In String2Date, change conditionals so Lee's heuristic for dates
; near the beginning or end of the century is used for 7.0 as well
; as ROM; skip definition of buildLevel (done in ScriptPriv.a).
; <1.9> 6/13/89 PKE (ROM & 7.0 only) Fix bug introduced by 1.6 below: In
; InitDateCache, lock itl0 & itl1 around direct or indirect calls
; to Block2String, which now calls LwrString and can move memory.
; <1.8> 6/9/89 PKE Fix InitDateCache bug that could trash random memory (BRC
; #50472).
; <1.7> 6/4/89 PKE Modify ValidDate and ToggleDate to check genCdevRangeBit flag
; and restrict valid dates to the Gregorian range 1920-2019 (or
; equivalent range in another calendar), as in General CDEV. Note:
; these changes were originally checked in on 5/25/89 as version
; 1.6, but the EASE version list didn't get updated. Consequently,
; (1) that version couldn't be checked out, and (2) the next
; checkout/checkin sequence resulted in the new version 1.6 below,
; which didn't have these changes.
; <1.6> 5/30/89 PKE (New ROMs & System 7.0 only) Replace UprString calls in routines
; that already move memory with calls to enhanced LwrString for
; localizable uppercasing.
; <1.5> 5/2/89 PKE Change CPU test in LongDiv to work properly for 68030 (BRC
; 35696); for ROM, replace test with conditionals that select the
; right code.
; <1.4> 4/7/89 PKE Modified ValidDate to compare LongDateRec fields from pm to era
; (was from era to weekOfYear, but undocumented): fixes the "2/29"
; problem in ToggleDate. Eliminated the ValidDate code
; (ROM/BigBang only) restricting hour to 0-11 if twelveHourBit
; set; check pm field instead, so hour will always be 0-23.
; Modified ToggleDate to mask out togFlags bits for LongDateRec
; fields it can't deal with; to place tighter restrictions on
; toggling by char in numeric fields (only $30-$39 and $b0-$b9
; allowed); and to handle 12-hour time in various ways with the
; addition of 3 flag bits. Fixed bug in LongSecs2Date for negative
; LongSecs.
; <1.3> 2/21/89 PKE Replaced with RomProj version, which already had system and Rom
; sources merged.
; (EASE ROMproj history below)
; <1.5> 2/21/89 PKE Fix up includes: always use include 'inc.sum.a'.
; <1.4> 2/14/89 PKE Updated to use MPW 3.0 final ScriptEqu.a equate names
; <1.3> 2/3/89 PKE Merged with current system sources (CCH's 01/16/1989 merge of
; 6.0.3 and 7.0 sources, done in RES.sys:smgr)
; <1.2> 11/14/88 PKE Synchronize EASE and Projector
; <1.1> 11/11/88 CCH Fixed Header.
; <1.0> 11/9/88 CCH Adding to EASE.
; (old EASE ROMproj history below)
; <1.8> 10/27/88 LDC Mods by Carl Hewitt and Brian McGhie in the process of putting
; Script Manager in ROM
; (EASE SYSproj history below)
; <1.2> 2/14/89 PKE Updated to use MPW 3.0 final ScriptEqu.a equates
; <1.1> 1/16/89 CCH Merged 6.0.3 final sources into 7.0.
; <1.0> 11/16/88 CCH Added to EASE.
; (pre-EASE history below)
; 10/12/88 ldc removed longDay, etc.
; 10/10/88 ldc include 'inc.sum.d'
; 9/30/88 ldc Added check for 12 hour time using #12HourBit in ValidDate
; 9/27/88 ldc Changed heuristic for determining when input year less than 100
; belongs in previous, current or next century
; 7/25/88 ldc Changed error equ names per Keithen

;========================IMPORTANT NOTE,POTENTIAL DANGER===================================
;
; The Data structure below is actually 6 bytes longer than the size of a
; DateCacheRecord. Initially, I fixed it so that the Record fit within 512 bytes
; but that change forced very large patches to String2Date and String2Time in the
; aurora and esprit ROMs.
;
; Since these patches were large and required a fair amount of change to ScriptMgrROMPatch.a
; we rethought fixing the cache so that it fit into 512 bytes and instead opted
; for keeping the fields in identical offsets.
;
; This is not as bad as it sounds (although it is bad, let there be no doubt about that)
; since the last 32 bytes of a tokenBlock are reserved and at this time (7.0 and earlier)
; are neither read from nor written to. For that reason, the fact that the declaration
; below is 6 bytes longer than the memory provided for it is only a forgiveable bit
; of forgetfulness.
;
; However, do NOT read or write any values past the itlResource field of the token block.
; And do NOT do what inside mac and the published headers say to do which is zero out
; the last 32 bytes of the token block. Doing that will TRASH memory. DON'T DO IT.
