when you connect to multiple servers each is givin a connection ID in order ....but say you had 3 server connections the $cid would return 1 2 3. if you droped connection2 and closed its status window and then opened a new status and made a 3ed connection the return in $cid would end up being 1 3 4 instead 1 2 3 like it was to start with. same applies with $scid and /scid for commands however there is a another identifier called $scon and command called /scon ....when using the $scon it keeps the 1 2 3 as 1 2 3 if you close connection and its status window and then make another and reconnect. it would be handy if there was a $con rather then making a custome identifier to do its job.
