The  Send  Escape Message  4  command  allows  you to  send  an  escape
message  using  QCMDEXC  or  similar  functions.   The  system  command
SNDPGMMSG  or other  TAA SNDESCMSGx  commands require  that the command
be in a  CL program.   SNDESCMSG4 may  be used from  a Command Exit  to
cause an escape message.

A typical command would be:

         SNDESCMSG4   MSG('...')

The  message  is  sent  as  message  ID TAA1020  from  the  TAAMSGF  in
TAATOOL.     The  second  level  text  identifies  it  as  coming  from
SNDESCMSG4.

Differences with other methods of sending escape messages
---------------------------------------------------------

The intent of SNDESCMSG4 is  that it can be  used as the command to  be
executed in a command exit program (see the TAA Tool CMDEXIT).

The system SNDPGMMSG  command and the other TAA  SNDESCMSG commands may
only be  used in a CL  program.  You cannot execute  one of these types
of commands in  a function  such as QCMDEXC  or in  the return  command
for a command exit program.

SNDESCMSG4 is not restricted  to CL program use.   Consequently, it may
be used whenever  an escape message must be  sent using a function like
QCMDEXC.
