Description

   Use the RELEASE command to release any messages previously marked
   as held, re-enter them in the queue cache database, and run the
   associated channel so the messages can be processed. Messages
   which have been held can be listed with the DIRECTORY/HELD
   command.

   The messages to be released are specified by their message
   identification numbers shown by the most recent DIRECTORY
   command. That number appears in the leftmost column of the
   DIRECTORY command listing. Ambiguous message numbers must be
   qualified by the proper channel name with the /CHANNEL qualifier.
