Syntax: +COMSET/DEFINE <name of set>=<list of channels>
This command creates a new channel set (or replaces an existing one if one of
the same name already exists; or deletes an existing one if one already
exists and <list of channels> is empty). <name of set> is a case-
insensitive text string. The rules for a legal name are the same as the
rules for legal attribute names. (No spaces and no special characters.)
<list of channels> is a space-separated list of the full names of all the
channels to be included in the set. You will receive an error message for
any illegal channels. Actually this command simply creates an attribute on
you named COMSET_<name of set> which contains <list of channels> as its
text. Users familiar with how to set attributes on themselves may wish to
simply set the attribute themselves and forget about this command and the
other +COMSET defining commands.
