To start the monday:

Does anybody know how many times a procedure
can be called recursively ??

I have a small program which gives problems if its
called more then 20 times

Hope someone can help me, the manual couldn't

Cheers,

The problem is that's in recursivly used procedure all variables inside
will be duplicated as many the routine is called.
For example if you call it 20 times as you say and you like to define
inside an array of 1000 elements then the memory is allocated
20*1000*[type] bytes.

If you have big and many arrays inside your recursive called routine you
will get in trouble.
