I've got a simple code which uses the ANSI and MacTraps
library. I am using Think C 4.0.2, and it runs fine under the
debugger. It also works fine when I compile it with the "Smark Link"
turned off.
When I turn on Smart Link, the code crashes on Launch before
it even gets to the first statement (I put a "Debugger()" trap in to
see if it got to line 2).
I use only the sprintf, atoi, and strlen routines, so naturally
my "unsmart" linked code is considerably larger...
Has this happened to anyone? Any suggestions appreciated.

Since you're on the mac, take advantage of it when you can! The only major routine that you may miss is sprintf, but once you write some code to take the place of sprintf you won't (IMHO) care. For atoi, use StringToNum. If you are using strlen (and I do, myself), only include the .c source file rather than the entire ANSI library. The only routine I've ever wished for was a pstrcat, so here's one I use: pascal void pstrcat(Str255 destStr, Str255 srcStr) { long toCopy = srcStr[0]; if (toCopy + destStr[0] > 255) toCopy = 255 - destStr[0]; BlockMove((Ptr) &srcStr[1], (Ptr) &destStr[destStr[0]+1], toCopy); destStr[0] += (char) toCopy; } > Has this happened to anyone? Any suggestions appreciated. Yes, and I was also using sprintf. I removed that, and everything worked. You have to remember than sprintf does a bunch of work, and sometimes that work is "under the cover of darkness"... -- ----------------------------------------------------------------------------- | Glenn L.
