Response message: List of “forbidden” channels
The :FCHannels <list> command is used to define a list of channels that cannot be closed. The
following examples demonstrate various forms for expressing a forblist:
Forblist
1!1 Single channel (Slot 1, Channel 1).
1!6, 1!18, 2!3!6 Channels separated by commas.
1!2:1!10 Range of channels (2 through 10).
1!2:1!10, 1!20 Range entry and single entry separated by commas.
M36 Channel pattern stored at memory location M36.
A “forbidden” channel list can be cancelled by sending an empty forblist as follows:
:fch (@)
If you specify a channel to be restricted and it is already included in the Scan List and/or a Chan-
nel Pattern, then the entire Scan List and/or Channel Pattern is cleared (lost).
10 OUTPUT 707; “:fch (@ 1!1, 1!4); fch?”
20 ENTER 707; A$
30 PRINT A$
40 END
Line 10 Define the “forbidden” channel list and query the the list.
Line 20 Address the Model 7001 to talk.
