<div><p>This describes the format in which elements in a list within a
|
||
|
|
list are passed when a command is run using CL or a high-level language.</p>
|
||
|
|
<div class="section"> <p>When a command is run using CL or HLL, a list within a list is
|
||
|
|
passed to the command processing program in the following format:</p>
|
||
|
|
<br /><img src="rbafn534.gif" alt="When a command is run using CL or HLL, a list within a list is passed to the command processing program in the this format." /><br /><p>The number of lists is passed
|
||
|
|
as a binary value of length 2. Following the number of lists, the displacement
|
||
|
|
to the lists is passed (not the values that were entered in the lists). Each
|
||
|
|
displacement is passed as a binary value of length 2 or length 4 depending
|
||
|
|
on the value of the LISTDSPL parameter.</p>
|
||
|
|
<p>The following example shows
|
||
|
|
a definition for a parameter KWD2 (which is a mixed list within a simple list)
|
||
|
|
how the parameter can be specified by the display station user,
|
||
|
|
and what is passed. The parameter definition is: </p>
|
||
|
|
<pre> PARM KWD(KWD2) TYPE(LIST) MAX(20) MIN(0) +
|
||
|
|
DFT(*NONE) SNGVAL(*NONE) LISTDSPL(*INT2)
|
||
|
|
LIST: ELEM TYPE(*CHAR) LEN(10) MIN(1) /*From value*/
|
||
|
|
ELEM TYPE(*CHAR) LEN(5) MIN(0) /*To value*/</pre>
|
||
|
|
<p>The display station user enters the KWD2 parameter as: </p>
|
||
|
|
<pre>KWD2((A B))</pre>
|
||
|
|
<p>The following is passed to the command processing program:</p>
|
||
|
|
<br /><img src="rbafn516.gif" alt="Example of what is passed to the command processing program when the display station user enters the KWD2 parameter as KWD2((A B))." /><br /><div class="p">If the display station user
|
||
|
|
enters the following instead: <pre>KWD2((A B) (C D))</pre>
|
||
|
|
the following is passed to the command processing program:</div>
|
||
|
|
<br /><img src="rbafn517.gif" alt="Example of what is passed to the command processing program when the display station user enters KWD2((A B) (C D))." /><br /><p>Lists within a list are passed
|
||
|
|
to the command processing program in the order n (the last one entered by
|
||
|
|
the display station user) to 1 (the first one entered by the display station
|
||
|
|
user). The displacements, however, are passed from 1 to n.</p>
|
||
|
|
<p>The following
|
||
|
|
is a more complex example of lists within lists. The parameter definition
|
||
|
|
is: </p>
|
||
|
|
<pre> PARM KWD(PARM1) TYPE(LIST3) MAX(25)
|
||

LIST3: ELEM TYPE(LIST4)

ELEM TYPE(*CHAR) LEN(3)
|

|
|
ELEM TYPE(*NAME) LEN(2) MAX(5)
|

LIST4: ELEM TYPE(*DEC) LEN(7 2)

ELEM TYPE(*TIME)

<div class="p">If the display station user enters the PARM1 parameter as shown
