I've dabbled a bit in programming with Lightspeed Pascal, and have run across an annoying, if not crippling problem. After I program for a while, the 'GO' option from the menu no longer will run the program; it states 'Program segment longer than 32K' or something like that (I haven't got it right in front of me). Needless to say, this is crippling. My program sufferes from errors of a bizarre nature, but debugging is impossible. Perhaps the 32K limit is itself the error. I don't know, but I understand that this is not exactly an unknown problem. I am working on a 512KE macintosh. First of all, is there any simple way to avoid this problem? Second of all, exactly what is it that is greater than 32K (not the code itself, certainly), and how does one correct this? Any advice and personal experiences are not only welcome but actively solicited. Please reply by e-mail, as I don't read this group all that often. My health and sanity depends on your aid! And some nice public domain programs may well result... Thanks a bunch.

You need to segment your application - each code segment has a maximum size of 32K for most development environments. MPW allows the developer to override the limit. Segmentation on Lightspeed Pascal is achieved by selecting view by segment by clicking in the upper right hand corner of the project window and then dragging source files from one segment to another. Note that with LSP your segmentation is performed at the source file level. With MPW the segmentation is performed at the procedure level. With segmentation, your application can be HUGE. Details on segmentation can be found in the Lightspeed Pascal manual (as in how to segment your project). Also details can be found in Inside Macintosh, or Knaster's books to name two sources off the top of my head. This is not be construed as any position on Lightspeed Pascal. This is not an advertisement for MPW. -- Byron Han, Communications Tool Apple Computer, Inc. -------------------------------------------------------------------------------- CSNet: han@apple.COM UUCP: {sun,voder,nsc,decwrl}!apple!han 408-973-6450 "Without Macintoshes, life itself would be impossible." - anon.

I tried to allocate memory using malloc() but apparently I am messing up the heap. the program looks like: #define size 32000 int *x; int i; char *malloc(); x = (int *) malloc(sizeof(int)*size); for (i = 0; i < size ; i++) x[i] = 0 ; Can anyone out there give me any advise on this problem?
