 Dear GPC Users,
 
 I'm trying to force the operating system to give my Pascal
 code a 2-MByte stack so I can solve a problem with a
 recursive routine. I have tried:
 
 const {for recursive routines}
     minstacksize: cardinal = 2000000; attribute
 (name = '_stklen');
 
 But that does not appear to work. Perhaps I am not trying
 hard enough. Am I on the right track?
 
 Yours, Kevan

     What you describe doing, I found in a FAQ, but the paragraphs around it mentioned DJGPP.  I'm not clear on what DJGPP is, or whether you're using it.  (I think I'm not using it -- I'm using MinGW.)

     The same place mentions using a program named "stubedit" to set the stack size:
          stubedit your_app.exe minstack=5000K
Do you have a "stubedit"?

     In doc/gpc/gpcc.txt there's mention of an option (switch?):
          Stack size: -$M<StackSize>

     "ld" has an option:
          --stack <size>
     I think you can get that through to "ld" by putting
          -Xlinker --stack=2000000
on your "gpc" command.

     I don't see "stklen" in my map file, but I wonder whether you need more or fewer underscores.
(Maybe "attribute(name=) used to "help" you by prepending an underscore, but has since been changed to do exactly what you tell it to do.)

     I haven't tried any of these things.
