;
; Change History (most recent first):
;
; <15> 11/17/92 PKE Change includes so that we can give this file out to localizers.
; Move SetClass, DumpCharTable, setByte, and SetRow macros to new
; IntlResourcesPriv.a.
; <14> 6/17/92 HA #1020127,<PKE>: Changed "¢" to be mapped to a postNum class
; instead of preNum, in class mapping table of FindWord (wrTable).
; So clicking on a run of numbers followed by ¢ will select the
; whole as one word.
; <13> 4/14/92 JSM Get rid of all SysVers conditionals.
; <12> 3/3/92 PKE #1021909, CubeE: Fix error in word select tables for non-break
; space handling.
; <11> 1/10/91 PKE (csd) Adapt to change in ScriptEqu.a: change “ring” to
; “ringMark”.
; <10> 12/10/90 PKE (VL) Change word break tables to fix old bug in which a
; non-breaking space glues whitespace to anything else. Now it
; only glues it to other whitespace.
; <9> 9/17/90 PKE Use formerly-reserved field in version 7 wordTable and wrapTable
; headers to store length of those tables; makes the tables ever
; so much nicer to DeRez. Touched up previous comment.
; <8> 9/17/90 SMB (PKE) Use formerly-reserved field in resource header for format
; code. A value >= 1 indicates that the length fields, etc. are
; present.
; <7> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
; six-point-oh-seven to six-point-oh-six.
; <5> 3/26/90 PKE Changed to also include 7.0 header extensions if
; romanDoSimpleScripts is true (which is now the case for 6.0.6).
; <4> 3/21/90 SMB Adding FindScriptTable to itl2 in a previously reserved space
; (by simply adding a comment!).
; <3> 3/2/90 PKE Changed word select definition in 7.0 to include letter-number
; as well as number-letter (already changed for 6.x).
; <2> 2/1/90 PKE NEEDED FOR 6.0.5: Change word select definition in 6.x to
; include letter-number as well as number-letter. Makes word
; select in TextEdit 3.0 act more like old TextEdit. This partly
; addresses BRC #58143. ALSO: 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)
; <2.3> 9/19/89 PKE Add length fields to header, fill in wordTableLen and
; wrapTableLen. Rearranged headers for 7.0 break tables to match
; new interfaces.
; <2.2> 9/5/89 PKE Now always use new-format FindWord tables for 7.0; other changes
; solved the problem that led to the silly forNFindWord
; conditional.
; <2.1> 9/4/89 PKE Add new-format FindWord tables for 7.0, but conditionalize them
; on forNFindWord, since will only be using them for testing at
; the moment.
; <2.0> 8/26/89 PKE Deleted load 'nEqu.d'. Changed references to newItl2Tables
; symbol to use SysVers instead, deleted newItl2Tables symbol.
; <1.9> 5/30/89 PKE Remove support in 6.0.4 for double-acute accent.
; <1.8> 4/12/89 PKE Added version number; fixed DumpCharTable macro for &index=0.
; <1.7> 3/29/89 PKE Add NoMarkList to SetClass & DumpCharTable macros; replace
; LowerNoMarkList table with NoMarkList table in itl2. LwrString
; can only use 4 out of the 5 possible conversions we might want,
; and the LowerNoMark conversion is the least useful.
; <1.6> 3/13/89 PKE Changed back to old order of offsets to tables (would have
; caused too many problems with existing prototypes).
; <1.5> 3/12/89 PKE Added LowerNoMarkList table; changed SetClass and DumpCharTable
; macros to accomodate this and to set UpperNoMarkList and
; LowerNoMarkList table values for all characters; supplied the
; additional data for the SetClass macro calls; fixed handling of
; Ø & ø (when stripping diacritics, they now go to O & o). Changed
; order of offsets to CharType/Transliterate/FindWord tables.
; <1.4> 3/10/89 PKE Add fi,fl to CharType/Transliterate tables
; <1.3> 3/5/89 PKE Conditionalized table changes that support character set
; extensions in Sys $604 and up; added German 'ß' support as part
; of these changes.
; <1.2> 2/21/89 PKE Extended to include CharType/Transliterate/FindWord tables from
; itlR. Fixed a problem introduced by use of new MPW equates: the
; itl2 offset equates defined in ScriptEqu.a replace the address
; offsets in this file, so change the offsets here to itl2XXXX.
; <1.1> 2/14/89 PKE Updated to use MPW 3.0 final ScriptEqu.a equate names
; <1.0> 11/16/88 CCH Added to EASE.
;
; (itlr history below, before it was merged in here)
; 10/18/88 ldc Moved word break and word wrap tables from RomanUtil.a
; 9/23/88 ldc changed lower casing rule for dotless i, added UpperNoMarkList
; for lower to upper casing without diacritics
; 7/12/88 ldc Added extensions of Macintosh character set
; 6/14/88 ldc Broke out from RomanUtil.a
;
; (old itl2 history below)
; 11/20/86 jdt Removed standard equates load. Renamed this file to prevent file
; name collisions.
; 9/18/86 JDT Roman package hooks are now also used by a switch-launched
; international system. And loving it.
; 8/28/86 JDT Mercilessly axed for the Roman script hook routines. The Roman
; package hooks do absolutely nothing. And they enjoy it.
; 8/27/86 MED Fixed extension bar.
; 8/24/86 MED Broke out from Intl, using $$Resource.
