|
|
<div><p>This example shows how to define and create a command that deletes
|
|
program objects and source members.</p>
|
|
<div class="section"> <p>You can create a command to delete HLL programs and their corresponding
|
|
source members.</p>
|
|
<p>The command definition statements for the command named
|
|
DPS are: </p>
|
|
<pre>CMD PROMPT ('Delete Program and Source')
|
|
PARM KWD(PGM) TYPE(*NAME) LEN(10) PROMPT('Program Name')</pre>
|
|
<p>The command processing program is written assuming that the
|
|
name of the program and the source file member are the same. Additionally,
|
|
you have to use the IBM-supplied source files of QCLSRC, QRPGSRC, and QCBLSRC.
|
|
The program also assumes that both the program and the source file are on
|
|
the library list. If you cannot open the program, the system sends an information
|
|
message, and the command attempts to remove the source member. If the source
|
|
member does not exist, the system sends an escape message. The command processing
|
|
program is:</p>
