<h1 class="topictitle1">ROLLUP/ROLLDOWN (Roll Up/Roll Down) keywords for display files</h1>
<div><p>Use these file- or record-level keywords to specify that you want
to use your program to handle any situation where the workstation user has
pressed the Roll Up or Roll Down keys and the <span class="keyword">i5/OS™</span> operating
system cannot move the text lines on the display. </p>
<div class="section"><p>If this situation occurs and you have not specified this keyword
(whichever one is appropriate), the <span class="keyword">i5/OS</span> operating
system sends an error message indicating that the key is not valid at that
time.</p>
<p>See the <a href="s36env.htm">System/36 environment considerations for display files</a> topic for special considerations
when specifying the ROLLUP/ROLLDOWN keywords in files that are used in the System/36™ environment.</p>
<div class="p">The
format for each of these keywords is: <pre>ROLLUP[(response-indicator ['text'])]
ROLLDOWN[(response-indicator ['text'])]</pre>
</div>
<p>You can specify
a response indicator with these keywords. If you do, and the appropriate paging
key is pressed, the <span class="keyword">i5/OS</span> operating
system sets on the specified response indicator within the input record and
returns control to your program after it processes the input data. If you
do not specify a response indicator and the specified paging key is pressed,
the <span class="keyword">i5/OS</span> operating system
performs normal input record processing.</p>
<p>The optional text is included
on the computer printout created at program compilation to explain the intended
use of the indicator. This text functions only as a comment in the file or
program. The single quotation marks are required. If you specify more than
50 characters between the single quotation marks, the text is truncated to
50 characters on the program computer printout.</p>
<p>These keys cause data
to be returned from the display device to your program (similar to command
function (CF) and Enter keys).</p>
<p>The PAGEDOWN keyword cannot be specified
with ROLLUP. The PAGEUP keyword cannot be specified with ROLLDOWN.</p>
<div class="note"><span class="notetitle">Note:</span> The
ROLLUP keyword is the same as the PAGEDOWN keyword. The ROLLDOWN keyword is
the same as the PAGEUP keyword. Roll is the same as page.</div>
<p>If the <span class="keyword">i5/OS</span> operating system is performing
the paging function for subfiles (SFLSIZ value does not equal SFLPAG value),
you do not need to specify these keywords. For a description of what happens
when ROLLUP and ROLLDOWN are specified for a subfile, see the <a href="rzakcmstdfsfrol.htm">SFLROLVAL (Subfile Roll Value) keyword for display files</a> topic.</p>
<p>Option
indicators are valid for these keywords.</p>
</div>
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
the ROLLUP and ROLLDOWN keywords.</p>
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
00010A N64 ROLLDOWN(52 'Roll Down')
