YeahBut, you don't wanna go there, because SAS is not written to support
recursion.
you'll end up spending more time doing workarounds.

RTFM on SAS functions. There are a whole bunch of round flat things, with
holes in the middle -- also known as 'wheels' -- already invented by SI.
Imagine our surprise!  LOL

You'll quickly run into the machine limits of register usage, nesting
levels, etc.
all kinds of majorly geek reasons NOT to go there.

But if pressed I could dig out my fibonacci programs.
which are kludges, at best.

take a look at the SAS Toolkit.
