<h1 class="topictitle1">ITERATE command</h1>
<div><p>The <span class="cmdname">Iterate (ITERATE)</span> command can be used to
skip the remaining commands in an active DOWHILE, DOUNTIL, or DOFOR group. </p>
<div class="section"><p>ITERATE is not valid with simple DO command groups.</p>
<p>An <span class="cmdname">Iterate
(ITERATE)</span> command without a label will skip to the ENDDO of the
innermost active DO group. Specifying a label skips to the ENDDO of the DO
associated with the label.</p>
<p>The following illustrates use of the <span class="cmdname">Iterate
(ITERATE)</span> command:</p>
<pre>DO_1:
DO_2:DOWHILE &amp;LGL
DO_3: DOFOR &amp;INT FROM(0) TO(99)
.
.
.
IF (&amp;A *EQ 12) THEN (ITERATE DO_1)
.
. /* Not processed if &amp;A equals 12 */
.
IF (&amp;A *GT 12) ITERATE
.
. /* Not processed if &amp;A greater than 12 */
.
ENDDO
.
.
.
IF (&amp;A *LT 0) (ITERATE DO_1)
.
. /* Not processed if &amp;A less than zero */
.
ENDDO
</pre>
<p>In this example, the labels DO_1 and DO_2 are associated with
the DOWHILE group. They can be specified on an <span class="cmdname">Iterate (ITERATE)</span> command
appearing in either the DOWHILE or DOFOR group. When &amp;A is equal to 12,
the ITERATE DO_1 command is run. Processing continues at the ENDDO associated
with the DOWHILE command. The value of &amp;LGL is evaluated and, if true,
continues with the DOFOR following the DOWHILE. If &amp;LGL is false, processing
continues with the CL command following the second ENDDO.</p>
<p>If &amp;A
is not equal to 12 but is greater than 12, processing continues with the ENDDO
of the DOFOR group. The value of &amp;INT is incremented and compared to
the ending value of 99. If &amp;INT is less than or equal to 99, processing
continues with the first command following the <span class="cmdname">Do For (DOFOR)</span> command.
If &amp;INT is greater than 99, processing continues with the next command
following the first ENDDO.</p>
<p>When the third IF command is processed and &amp;A
is less than zero, processing continues with the second ENDDO. The value
of &amp;LGL is evaluated and, if false, control passes to the command following
the ENDDO. If true, processing resumes with the <span class="cmdname">Do For (DOFOR)</span> command
following the DOWHILE.</p>
