The Display Command  Help command displays  the help text for  a system
or  user command  including  commands the  user is  not  authorized to.
The  command is  useful for  such functions  as attempting  to simulate
the system command line function.  The QCAPCMD API is used.

The typical command would be:

            DSPCMDHLP   CMD(xxx)

The command help would be displayed.

The command is  not prompted for and  is not run.   Only the help  text
is displayed.

Security considerations
-----------------------

The command processing  program adopts the authority of  QSECOFR.  This
allows any user to display the help text of any command.

There  is no capability to run  a command from the  display of the help
text.  Pressing  Enter causes a  return to the  invoking function  such
as a command line.
