<h1 class="topictitle1">Write a command processing program or procedure</h1>
|
|
<div><p>A command processing program (CPP) is a program that processes
|
|
a command. This program performs some validity checking and processes the
|
|
command so that the requested function is performed. </p>
|
|
<div class="section"> <p>A command processing program (CPP) can be a CL or HLL program,
|
|
or a REXX procedure. Programs written in CL or HLL can also be called directly
|
|
with the <span class="cmdname">Call (CALL)</span> command. REXX procedures can be called
|
|
directly using the <span class="cmdname">Start REXX Procedure (STRREXPRC)</span> command.
|
|
The command processing program does not need to exist when the <span class="cmdname">Create
|
|
Command (CRTCMD)</span> command is run. If *LIBL is used as the library
|
|
qualifier, the library list is used to find the command processing program
|
|
when the created command is run.</p>
|
|
<p>Messages issued as a result of running
|
|
the command processing program can be sent to the job message queue and automatically
|
|
displayed or printed. You can send displays to the requesting display station.
|
|
</p>

|
<div class="note"><span class="notetitle">Note:</span> <ol><li>The parameters defined on the command are passed individually in the order
|
|
they were defined (the PARM statement order).</li>
|

<li>Decimal values are passed to HLL and CL programs as packed decimal values

of the length specified in the PARM statement.</li>
