<div><p>This example shows how to define and create a command that provides
|
||
|
|
defaults for an IBM-supplied command.</p>
|
||
|
|
<div class="section"> <p>You can create a command that provides defaults for an IBM-supplied
|
||
|
|
command and reduces the entries that the display station user must make.
|
||
|
|
For example, you could create a <span class="cmdname">Save Library on Tape (SAVLIBTAP)</span> command
|
||
|
|
that initializes a tape and saves a library on the tape device TAPE1. This
|
||
|
|
command provides defaults for the standard <span class="cmdname">Save Library (SAVLIB</span>)
|
||
|
|
command parameters and requires the display station user to specify only the
|
||
|
|
library name.</p>
|
||
|
|
<p>The command definition statements for the <span class="cmdname">Save
|
||
|
|
Library on Tape (SAVLIBTAP)</span> command are: </p>
|
||
|
|
<pre>CMD PROMPT('Save Library to Tape')
|
||
|
|
PARM KWD(LIB) TYPE(*NAME) LEN(10) MIN(1) +
|
||
|
|
PROMPT('Library Name')</pre>
|
||
|
|
<p>The command processing program is:</p>
|
||
|
|
<pre>PGM PARM(&LIB)
|
||
|
|
DCL &LIB TYPE(*CHAR) LEN(10)
|
||
|
|
INZTAP DEV(TAPE1) CHECK(*NO)
|
||
|
|
SAVLIB LIB(&LIB) DEV(TAPE1)
|
||
|
|
ENDPGM</pre>
|
||
|
|
<p>The <span class="cmdname">Create Command (CRTCMD)</span> command is:
|
||
|
|
</p>
|
||
|
|
<pre>CRTCMD CMD(SAVLIBTAP) PGM(SAVLIBTAP) SRCMBR(SAVLIBTAP)</pre>
