I use the mbbo to configure some of my timing generator.
For example, I can select 'internal' or 'external' trigger.
For each of those settings, I need to send over GPIB a specific command.
I noticed that a mbbo record is quite a nice way to do that.

The only thing is that in the record we cannot input clearly which
command to send when the mbbo is set to 0 or 1.
Obviously, I could use the OUT field to pass all of the 16 commands
(mbbo can have up to 16 values/strings). But then I could potentially
hit the limit on the length of that field (40 chars?) and the command
are not clearly associated with a 'state' string (the association of
field in the Db file must be done in the driver code - Not really
readable!).
The other method I have found is to use a soft mbbo to a sequencer
(SELM=specified and DOLx=my commands) that output on a Stringout record.
Is anybody using anything else or a smarter way?
