Since Lightspeed C Version 2.0 is not yet available, I wanted to ask people on the net who use LSC 1.02 whether they have Libraries/Headers for interfacing to :- 1) MacinTalk - I have tried RelConv'ing SpeechAsm.Rel -> no luck with calls 2) Graf3D - " " " " Graf3D.Rel -> " " " " Also, has anybody got any *working* LSC code for using the List Manager? I have made no inroads - have you? Finally, has anyone heard of an Arabic (read - right-to-left) WP? Thanks in advance, Jason Haines

LightspeedC 2.? *is* available now. My copy arrived December 26th.
I suppose we get it here in the United States before you people in
Australia get it, but I suppose you can always just throw another
shrimp on the barbie or something while you wait... :-)

Actually, if you've registered your older version of Lightspeed C you should be receiving version 2.0 in the mail any day now. I and several others in the bay area already have. 2.0 has the List manager interface built in so you shouldn't have any problems with that. For right to left word processing their is something called, believe it or not, "Right-To-Left" or something very close to that. Sorry I don't have more details. Call ComputerWare, if they don't still carry they at least used to. -- David W. Berry dwb@well.uucp dwb@Delphi dwb@GEnie 293-0752@408.MaBell

By all means, check this against the IM and LSC assembly sections before using it -- my memory isn't always very reliable. Also, I met someone last summer who showed me a patch he'd written to convert MacWrite to right-to-left (for Hebrew, not Arabic, but I expect the principle is the same). I think it was installed and removed through a DA, and that he said it was public domain and available through the Boston Computer Society, but asked for a donation to MIT's Hillel House. Or maybe available through Hillel, but asked for a donation to the BCS? --Tom Lippincott ..ihnp4!gargoyle!sphinx!fdot "Oh Yeah! Sez who?" -- Immanuel Kant, _The Critique of Pure Reason_

Be warned that anything you write with this hack will probably FAIL on a 68020 machine due to the prefetch effect of the cache. Self modifying code is usually something to be avoided, but if you must do it you've got to take into account prefetch queues, caches, et. al. If you must do this, try pushing your calculated code onto the stack and calling it there. Also, if LSC works like Aztec, the caller deallocates the pushed parameters when the callee returns. Since the above fragment eats the trap word you should expect the stack to get hosed. +----------------+ ! II CCCCCC ! Jim Cathey ! II SSSSCC ! ISC Systems Corp. ! II CC ! Spokane, WA ! IISSSS CC !
