Hi Ed,
<< I've created a small program to scan emails from my inbox. It works
fine until I try and remove them. Without the REMOVE command, it parses
all emails in the inbox. Once I add the REMOVE command, it takes several
passes to get everything cleared out. >>
It's a combination of FORALL and REMOVE that's trippnig you up. FORALL steps
through the series (you can see the source for it BTW. It's a mezzanine)
using NEXT and REMOVE returns the series at the location *after* the remove,
so you're skipping every other element when you combine them.
>> b: [1 2 3 4 5 6]
== [1 2 3 4 5 6]
>> forall b [print first b remove b]
1
3
5
HTH!
