Statements/parameters for MPFLSTxx
msgidIdentifies a message or group of messages to be processed. The
msgid consists
of:

   - A complete message identifier of one to ten characters. This is known
   as a *specific* message identifier.
   - A message prefix, which is a portion of the message identifier,
   followed by an asterisk(*). This is known as a *generic* message
   identifier.
   - A single quotation mark (') is *not* a valid character in a message
   identifier.

A message identifier begins with the first non-blank character of the
message text and continues until the next blank

​Use the allowed maximum of 10 characters, but make the last of those be an
asterisk. This makes the msgid be a "generic" which will match _all_ msgids
which match the leading characters. You must then have the code which runs
when the match occur compare the actual, entire, msgid.​

​A space unconditionally terminates the msgid. So something like "ABB CDDF"
has a msgid of "ABB".​

I have a theory that it's impossible to prove anything, but I can't prove
it.
