A QMF message identification. QMF attempts to find message
help associated with messageid. If found, it is displayed. If not,
an error message is displayed. In QMF batch jobs, the message contains
the message number in the L trace file.
A message ID must begin with the three letters "DSQ" followed
by a five digit number, for example: DSQ20114. DB2 QMF Messages and Codes lists message
numbers and text.
