<h1 class="topictitle1">PSHBTNFLD (Push Button Field) keyword for display files</h1>
|
|||
|
|
<div><p>Use this field-level keyword to define a field as a push button
|
|||
|
|
field.</p>
|
|||
|
|
<div class="section"><p>A push button field is a field that contains a fixed number of
|
|||
|
|
push buttons from which a user can select. The field appears as a list of
|
|||
|
|
command keys each enclosed with '<>' or as a group of push buttons.</p>
|
|||
|
|
<div class="p">The
|
|||
|
|
format of the keyword is: <pre>PSHBTNFLD[([*NORSTCSR ∨ *RSTCSR]
|
|||
|
|
[(*NUMCOL nbr-of-cols) ∨ (*NUMROW nbr-of-rows)]
|
|||
|
|
[(*GUTTER gutter-width)])]</pre>
|
|||
|
|
</div>
|
|||
|
|
<p>The parameters are optional and
|
|||
|
|
can be entered in any order. When no parameter is specified, the push button
|
|||
|
|
field choices are arranged horizontally. *GUTTER parameter is set to 3 as
|
|||
|
|
default and the field will be displayed using as many lines as it takes to
|
|||
|
|
display all of the choices. There will be 3 spaces between each choice.</p>
|
|||
|
|
<p>The
|
|||
|
|
RSTCSR parameter specifies whether the arrow keys should be allowed to move
|
|||
|
|
the selection cursor outside of the field. *RSTCSR specifies that the arrow
|
|||
|
|
keys will not cause the selection cursor to move outside of the push-button
|
|||
|
|
field. *NORSTCSR specifies that the arrow keys will cause the selection cursor
|
|||
|
|
to leave the field. The default is *NORSTCSR.</p>
|
|||
|
|
<div class="p">The *NUMCOL parameter
|
|||
|
|
specifies that this field should be displayed in multiple columns with the
|
|||
|
|
choices arranged across the columns in this manner: <pre>< F1 > < F2 > < F3 >
|
|||
|
|
< F4 > < F5 > < F6 >
|
|||
|
|
< F7 > < F8 > < F9 ></pre>
|
|||
|
|
</div>
|
|||
|
|
<p>Nbr-of-rows
|
|||
|
|
specifies how many rows the push-button field should contain. Nbr-of-rows
|
|||
|
|
must be a positive integer and the entire single-choice push-button field
|
|||
|
|
must be able to fit on the display when placed in the specified number of
|
|||
|
|
rows.</p>
|
|||
|
|
<p>The *GUTTER parameter specifies the number of blanks to be placed
|
|||
|
|
between each column of the push-button field. Unlike the SNGCHCFLD keyword,
|
|||
|
|
it can be specified even if *NUMCOL or *NUMROW have not been specified. The
|
|||
|
|
gutter-width must be a positive integer. If *GUTTER is not specified, the
|
|||
|
|
default of gutter-width is set to three blanks. The gutter value must be a
|
|||
|
|
number greater than one.</p>
|
|||
|
|
<p>For more information about how to support different
|
|||
|
|
device configurations, see the <a href="../books/sc415715.pdf" target="_blank">Application Display Programming book</a><img src="wbpdf.gif" alt="Link to PDF" />.</p>
|
|||
|
|
<p>A field
|
|||
|
|
containing the PSHBTNFLD keyword must also contain one or more PSHBTNCHC keywords
|
|||
|
|
defining the choices for the field.</p>
|
|||
|
|
<p>The field containing the PSHBTNFLD
|
|||
|
|
keyword must be defined as an input-capable field with data type Y, length
|
|||
|
|
equal to 2, and decimal positions of 0. The position specified for the field
|
|||
|
|
is the position of the first push-button choice. For input, the field contains
|
|||
|
|
the number of the choice selected, or 0 if no choice was selected. For output,
|
|||
|
|
the value of the field is ignored.</p>
|
|||
|
|
<p>The following keywords can be specified
|
|||
|
|
on a field with the PSHBTNFLD keyword:</p>
