<h1 class="topictitle1">Use REXX for mixed lists</h1>
|
||
|
|
<div><p>This describes the format in which elements in a mixed list are
|
||
|
|
passed when a command is run using REXX.</p>
|
||
|
|
<div class="section"> <p>When a command is run using REXX, the elements in a mixed list
|
||
|
|
are passed to the command processing program in the following format where <samp class="codeph">valueN</samp> is
|
||
|
|
the last value in the mixed list.: </p>
|
||
|
|
<pre> . . . CMPVAL(value1 value2
|
||
|
|
. . . valueN) . . .</pre>
|
||
|
|
<p>If the user does not enter a value for an element,
|
||
|
|
a default value is passed. For example, if in the previous example, the user
|
||
|
|
enters a comparison value of QCMDI for the CMPVAL parameter, but does not
|
||
|
|
enter a value for the starting position, whose default value is 1, the following
|
||
|
|
is passed: </p>
|
||
|
|
<pre> . . . CMPVAL(QCMDI 1)
|
||
|
|
. . .</pre>
|
||
|
|
<p>Note that trailing blanks are not passed with REXX values.</p>
|
||
|
|
<p>When
|
||
|
|
a display station user enters a single value or when a single value is the
|
||
|
|
default for a mixed list, the value is passed as the first element in the
|
||
|
|
list. For example, if the display station user enters *ANY as a single value
|
||
|
|
for the parameter, the following is passed: </p>
|
||
|
|
<pre> . . . CMPVAL(*ANY) . . .</pre>
|
||
|
|
<p>Again note that trailing blanks are not passed with REXX values.</p>
|
||
|
|
<p>If
|
||
|
|
no default value is defined on the PARM statement for an optional parameter
|
||
|
|
and the first value of the list is required (MIN(1)), then the parameter itself
|
||
|
|
is not required. But if any element is specified, the first element is required.
|
||
|
|
In this case, if the command is entered without specifying a value for the
|
||
|
|
parameter, the following is passed: </p>
|
||
|
|
<pre> . . . CMPVAL() . . .</pre>
