recursive formula

[banAnnA]

I'd like to write a recursive formula to understand this principle better. I want the function to print something each time it passes. I tried to write such a thing before, but it only returns something (a number, eg.) and does not print while 'busy".

Can someone give me an example?

Here's a very, very simple example. This will probably get up into the thousands before the program stops with an out of stack space error:
[syntax="qbasic"]DEFINT A-Z

DIM SHARED RecursionNumber

RecursionNumber = 0

DoIt

END

SUB DoIt

RecursionNumber = RecursionNumber + 1

PRINT "This is recursion #"; RecursionNumber

DoIt

END SUB[/syntax]
