SIGNAL is a general purpose utility that allows you to use the VMS message
utility more effectively from within DCL.  With SIGNAL you can create your own
message files or use existing system messages and message files to display
messages to the user and control command procedure execution by issuing your own
warnings, errors, or severe errors.  See program description in SIGNAL.FOR for
addtional information.  Also, for a complete description of all the qualifiers,
there is a VMS help file (SIGNAL.HLP).  I have also included a demo command
procedure, DEMO.COM.  It isn't very fancy, but you should get an idea of how to
use SIGNAL by studying the com file.
