I am trying to build character case translation tables for a
single-byte character set using UprString(). I build a character
array with all 255 non-NUL values in it, then pass it to UprString().
I want UprString() to convert all alphabetic characters to upper case,
while leaving non-alphabetic characters alone. Based on the result of
this operation, I then build upper to lower and lower to upper
character translation tables. I also use the information to determine
whether a given character is a letter and not punctuation. If the
case of a character can be changed, then it is obviously not
punctuation.
Everything works fine, except that UprString() converts '`'
(back-quote) to lower case 'a'. This happens with System 5.0, System
6.0.3, and System D1-6.0.3 (Deutsch). I have tried it on a Mac Plus
and on a Mac II. Always, '`' -> 'a'. Most distressing.
I could use Transliterate() or LwrText() to build the same
tables, but these are not available on all Macs and I want this
particular code to be as compatible as possible.
Is this a bug in UprString()? What should I do? I suppose I
could write code to detect the inconsistency and attempt to correct
it... Are there any other bugs in this routine which manifest on
systems other than U.S. and Deutsch?

We have sent mail to MacDTS on this one, but have yet to recieve an answer...I'll give them a couple of days and them go over their heads to get the answer...It should be a good one ;-) -- +--------------------------------------------------+ Leonard Rosenthol | GEnie : MACgician Lazerware, inc. | MacNet: MACgician UUCP: svc@well.UUCP | ALink : D0025

At least it works correctly on U.S. and Deutsch systems I have, including doing '`' properly. LwrText is new, however, and I think you need System 6.0 for it to work. (One can use LwrText to generate a table for upper casing.) I decided to include a mechanism to allow users to override entries in the translation tables I generate, anyway. I found that even something as basic as an "ess-tset" (Deutsch double-s as in "Strassburg") doesn't count for a letter unless you have 6.0.4 and use the Script Manager. I also included a search for the anomalous triplet, '`' -> 'a' -> 'A', and demote the '`' to punctuation if found. Earle R. Horton
