# $EPIC: currchans.txt,v 220.127.116.11 2006/07/11 04:57:43 jnelson Exp $
Returns the current channels for each window connected to <server refnum>. If <server refnum> is -1, then $lastserver() is assumed.
If no arguments are passed, all current channels are returned.
This function returns each argument as “<server refnum> <channel>” in double quotes.
eval echo $currchans(1) /* returns "1 #epic" "1 #unix" */
(assuming there are two windows connected to server 1, with #epic in one window and #unix in the other)
