Thanks Holger,
I was able to modify my script to include copy/part port 1 and then add
some logic which got it working without a hitch and got rid of the past-end
message. The logic was just an added line:
if irc-input-buffer = block! [irc-input-buffer: to-string irc-input-buffer]
Paul Tretter
P.S. - This should probably get added to the /Core docs some day depending
on how it changes in the next release.
