Below I post the answer as given me by Mark Jason Dominus, the author of "Higher Order Perl" himself. This is the complete text of his reply to my e-mail, quoted here with permission.

I wanted to post it as warning of the kinds of problems one can run into when using recursion if one is not careful.

Oops, please don't be put off in the above post by the fact that I have two print_instructi on subroutines defined. This is not the case in practice. I just copied that code above the call to hanoi() without deleting it from below. Thanks.Leave a comment:

Error when using coderefs.

No current record after delete
I saw the keywords in my title elsewhere, but it didn't answer my question. In Access 2000 on WIndows XP Pro, I have a multiple table join query as the basis for a form.

How can I make it the current record? Thanks.
