I have always found the variables I want have still been available in the 'h'
extension. When setting ROOM, you could always try setting _ROOM or __ROOM
in case it is getting lost somewhere during a channel switch or inheritance.
You still gets its value using ${ROOM} and not ${_ROOM} etc.

See "show application set".

I assume the OP was setting ROOM himself, since he passed its value to
Meetme as an argument.

Also, an inspectino of the code shows that MeetMe does not set the variable
CONFNO. It refers to it in the description of the 'R' (record) option, but
in fact that part of the default filename is filled in directly from an
internal variable, and not put into the variable CONFNO.
