<h1 class="topictitle1">RELPOS (Relative Position) keyword in printer files</h1>
|
||
|
|
<div><p>Use this file-level keyword to indicate that when the <tt>+n</tt> form
|
||
|
|
of positioning a field is used, the fields subsequent to the first field in
|
||
|
|
the line are positioned relative to the end of the previous field. Without
|
||
|
|
the RELPOS keyword, the column number calculated at compile time is generally
|
||
|
|
relative to the beginning of the line.</p>
|
||
|
|
<div class="section"><p>This keyword has no parameters.</p>
|
||
|
|
<p>The <em>+n positioning</em> means
|
||
|
|
that, if you specify a location of a field in a record and the field is not
|
||
|
|
ignored, you can specify the location of subsequent fields within that record
|
||
|
|
by leaving the line number blank and specifying a plus value (<tt>+n</tt>)
|
||
|
|
for position entry 42 through 44. The plus value indicates the number of spaces
|
||
|
|
to be left between the end of the previous field and the beginning of the
|
||
|
|
field you are defining. The plus value must be in the range of 0 through 99.
|
||
|
|
If you specify a plus value, the line number entry must be blank. As soon
|
||
|
|
as the positions are calculated, the real values are stored and treated as
|
||
|
|
if they were hard-coded. This is a compile time function.</p>
|
||
|
|
<p>Specify DEVTYPE
|
||
|
|
(*AFPDS) on the CRTPRTF command when RELPOS is specified at the file level.
|
||
|
|
If DEVTYPE is changed to anything other than *AFPDS, the keyword is ignored
|
||
|
|
and a warning message is issued at print time.</p>
|
||
|
|
<p>Option indicators are
|
||
|
|
not valid for this keyword.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> The Print Services Facility™ (PSF)
