[REBOL] Submitted for your approval.
From: edanaii:cox at: 5-Aug-2002 18:57
All,
Here's a REBOL program I've been working on. It's almost complete, but I
still have a few things to do to it. Since this is my first *serious*
REBOL program, I'm submitting here for you to critique.
Please feel free to tear it apart.
One of the things I have not added is error handling. I'd also like
advice on that, like what can go wrong. I know for example that when I
try to open the mailbox, it may not be there. Naturally, I need to trap
that. What other events do I need to keep an eye on in order to manage
the mailbox?
Thanks in advance...
