Can anybody convert this recursive procedure to a non-recursive one?

The procedure is called, in the simplest way, with:
Call Permutation("string-to-permute").

On the one hand, yes, it can be unrolled, using some combination of
control structures.

On the other hand, *why* do you want it to be unrolled?

Why you ask me that?

It's pretty straightforward: What is the purpose of unrolling the recursive
procedure you posted? What are you trying to accomplish?

Here's a Google search that'll get you started:
