I'll try this and compare it to what Joe sent. Also looking at publib.0.39
that LIW started years back. Ideally, I think it's better to malloc space
because given my intended use, the strings could be relatively few ... or run
into the thousands.
Parenthetically, I'm trying to get use to kmail, and evolution, both of which
are hard to save the attachment-of. mutt is so much easier.
Thanks for the feedback. much appreciated,
