<div class="section"> <ul><li>A <em>keyword</em> is a name that identifies a function.</li>
|
||
|
|
<li>A <em>parameter</em> is an argument that identifies a value or set of values
|
||
|
|
you can use to tailor the function the keyword specifies. It is shown between
|
||
|
|
the parentheses on a keyword.</li>
|
||
|
|
<li>A <em>value</em> is an actual value that you can use for a parameter.</li>
|
||
|
|
<li>In the keyword descriptions, <em>this field</em> or <em>this record format</em> means
|
||
|
|
the field or record format that you are defining.</li>
|
||
|
|
<li>The expression <em>use this file- or record-level keyword</em> means the
|
||
|
|
keyword is valid only at the file or record level.</li>
|
||
|
|
<li><em>To specify a keyword</em> means to code the keyword in the DDS for a
|
||
|
|
file. This contrasts with <em>to select a keyword</em> or <em>when a keyword
|
||
|
|
is in effect</em>, both of which mean that any conditioning (such as one or
|
||
|
|
more option indicators) is satisfied when an application program issues an
|
||
|
|
input or output operation.</li>
|
||
|
|
<li><em>Current source</em> or <em>source you are defining</em> means the DDS
|
||
|
|
that together make up the description of one file.</li>
|
||
|
|
<li>In sample displays, character fields are shown as Xs and numeric fields
|
||
|
|
are shown as Ns.</li>
|
||
|
|
<li>The 5250 Work Station Feature is a feature of the OS/2<sup>®</sup> communications
|
||
|
|
manager that allows the personal computer to perform like a 5250 display station
|
||
|
|
and use functions of the IBM<sup>®</sup> <img src="eserver.gif" alt="eServer" /><span class="keyword">iSeries™</span> server.</li>
|
||
|
|
<li><em>Logical file</em> includes join logical files, simple logical files,
|
||
|
|
and multiple-format logical files.</li>
|
||
|
|
<li><em>Page</em> means to move information up or down on the display. <em>Roll</em> means
|
||
|
|
the same as page. <em>Paging keys</em> are the same as <em>roll keys</em>. The
|
||
|
|
PAGEDOWN keyword is the same as the ROLLUP keyword. The PAGEUP keyword is
|
||
|
|
the same as the ROLLDOWN keyword.</li>
