|
||
|
<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 &LGL
|
||
|
DO_3: DOFOR &INT FROM(0) TO(99)
|
||
|
.
|
||
|
.
|
||
|
.
|
||
|
IF (&A *EQ 12) THEN (ITERATE DO_1)
|
||
|
.
|
||
|
. /* Not processed if &A equals 12 */
|
||
|
.
|
||
|
IF (&A *GT 12) ITERATE
|
||
|
.
|
||
|
. /* Not processed if &A greater than 12 */
|
||
|
.
|
||
|
ENDDO
|
||
|
.
|
||
|
.
|
||
|
.
|
||
|
IF (&A *LT 0) (ITERATE DO_1)
|
||
|
.
|
||
|
. /* Not processed if &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 &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 &LGL is evaluated and, if true,
|
||
|
continues with the DOFOR following the DOWHILE. If &LGL is false, processing
|
||
|
continues with the CL command following the second ENDDO.</p>
|
||
|
<p>If &A
|
||
|
is not equal to 12 but is greater than 12, processing continues with the ENDDO
|
||
|
of the DOFOR group. The value of &INT is incremented and compared to
|
||
|
the ending value of 99. If &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 &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 &A
|
||
|
is less than zero, processing continues with the second ENDDO. The value
|
||
|
of &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>
