<h1 class="topictitle1">Condition for ICF files (positions 7 through 16)</h1>
|
|
<div><p><span>Positions 7 through 16 are a multiple-field
|
|
area in which you can specify option indicators.</span></p>
|
|
<div class="section"><p>Option indicators are 2-digit numbers from 01 to 99. Your program
|
|
can set option indicators on (hex F1) or off (hex F0) to select a keyword
|
|
for output operations. In ICF files, option indicators are valid only for
|
|
record- and file-level keywords.</p>
|
|
<p>A condition is an ANDed grouping of
|
|
two through nine indicators that must all be in effect (set off if the letter
|
|
N is specified; set on if N is not specified) before the keyword is selected.
|
|
You can specify a maximum of nine indicators for each condition and nine
|
|
conditions for each keyword. Therefore, a maximum of 81 indicators can be
|
|
specified for each keyword, when nine indicators are used with nine conditions.
|
|
An AND condition occurs when you specify a condition requiring that more than
|
|
one indicator must be on or off before the condition is satisfied. The first
|
|
indicator you specify, AND the second, AND the third, and so on, must all
|
|
be in effect before the condition is satisfied and the keyword is selected.
|
|
You must specify the keyword on the same line as the last (or only) set of
|
|
indicators specified.</p>
|
|
<p>You can also specify several conditions for a
|
|
keyword so that if any one of them is satisfied, the keyword is selected.
|
|
This is called an OR relationship. In an OR relationship, if the first condition
|
|
is satisfied, OR the second condition, OR the third condition, and so on,
|
|
the keyword is selected. Note that conditions within the OR relationship can
|
|
consist of just one indicator or can consist of several indicators ANDed together.
|
|
Indicators can be ANDed to form a condition. Conditions can be ORed to give
|
|
your program several ways to select the keyword.</p>
|
|
<div class="p">Specify the conditions
|
|
by entering the following values: <dl><dt class="dlterm">Position 7 (AND)</dt>
|
|
<dd>If you need more than three indicators to form an ANDed condition, specify
|
|
the indicators on the next line or lines. You can specify an A in position
|
|
7 on the second or following lines to continue the ANDed condition, or you
|
|
can leave it blank because A is the default.</dd>
|
|
<dt class="dlterm">Position 7 (OR)</dt>
|
|
<dd>If you specify several conditions that are to be ORed together, each condition
|
|
must start on a new line and each condition, except the first, must have an
|
|
O in position 7. An O specified for the first condition produces a warning
|
|
message, and that position is assumed to be blank.</dd>
|
|
<dt class="dlterm">Positions 8, 11, 14 (NOT)</dt>
|
|
<dd>If you want an indicator to be off instead of on to satisfy a condition,
|
|
specify an N in the position just preceding the indicator (position 8, 11,
|
|
or 14).</dd>
|
|
</dl>

</div>
|
|
<div class="section"><h4 class="sectiontitle">Condition more than one keyword for ICF files</h4><p>If
|
|
you want to condition one or more keywords, the last (or only) indicator must
|
|
appear on the same line as the keywords. If the conditioning applies to keywords
|
|
on more than one line, you must use keyword continuation for the indicators
|
|
to apply to all keywords. See the <a href="../dds/rbafpmstsyntax.htm">syntax rules</a> in the DDS Concept
|

information for details.</p>
