<div><p>Use this record-level keyword to define the shape, positioning,
|

and attributes for the line structure. This keyword defines whether the line

is erased, display, or not processed.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>GRDLIN((*POS([*DS3] [*DS4]
|
||

|
<p>The *POS parameter is
|
||
|
|
a required parameter. This parameter allows display size and conditioning
|
||
|
|
of the GRDLIN keyword. Coding *DS3 or *DS4 with the *POS parameter, you can
|
||
|
|
have 2 different start row, start column, and length values depending on the
|
||
|
|
display size being used. DSPSIZ keyword must be coded on the file level.</p>
|
||
|
|
<p>If
|
||
|
|
a field name is specified, the field must exist in the record format, data
|
||
|
|
type S, usage P, length of 3, and zero decimal positions.</p>
|
||
|
|
<div class="p">The type parameter
|
||
|
|
is a required parameter. The valid values for the type parameter are: <dl><dt><strong>Value</strong></dt>
|
||
|
|
<dd><strong>Meaning</strong></dd>
|
||
|
|
<dt class="dlterm">UPPER</dt>
|
||
|
|
<dd>Horizontal line on the upper character border</dd>
|
||
|
|
<dt class="dlterm">LOWER</dt>
|
||
|
|
<dd>Horizontal line on the lower character border</dd>
|
||
|
|
<dt class="dlterm">RIGHT</dt>
|
||
|
|
<dd>Vertical line on the right character border</dd>
|
||
|

<dt class="dlterm">LEFT</dt>

<dd>Vertical line on the left character border</dd>
|
||
|
|
</dl>
|
||
|
|
</div>
|
||
|
|
<p>The repeat parameter specifies the number of times the
|
||
|
|
line is to be repeated. The interval parameter specifies the number of character
|
||
|
|
spaces between the repeated lines.</p>
|
||
|
|
<p>The default for the type parameter
|
||
|
|
is upper. If neither the repeat value nor the interval value is coded, a single
|
||
|
|
grid line is drawn. The repeat and interval defaults are 1.</p>
|
||
|
|
<p>If a field
|
||
|
|
name is specified, the field must exist in the record format and must be defined
|
||
|
|
as data type S, usage P, and length greater than 3.</p>
|
||
|
|
<p>The *COLOR and *LINTYP
|
||
|
|
parameter defines the color and attributes of the box. P-fields
|
||
|
|
can be used to define or change the attributes at run time.</p>
|
||
|
|
<p>For more
|
||
|
|
information about the *COLOR and *LINTYP parameter, see the <a href="rzakcmstdfgrda.htm">GRDATR (Grid Attribute) keyword</a> topic.</p>
|
||
|
|
<p>If
|
||
|
|
NONE is defined by the GRDLIN keyword, the color set by the GRDATR keyword
|
||
|
|
will be used.</p>
|
||
|
|
<p>If a p-field is specified for either the COLOR or LINTYP
|
||
|
|
parameter, the field must exist in the record format. The field is defined
|
||
|
|
as data type A, usage P, and length of 1.</p>
|
||
|
|
<p>The *CONTROL parameter specifies
|
||
|
|
the whether the GRDLIN is to be displayed, erased from the screen, or ignored
|
||
|
|
(similar to optioning off the keyword). The field must exist in the record
|
||
|
|
format and must be defined as data type S, usage P, and length of 1. If the
|
||
|
|
p-field is set to 0, the grid line will be displayed. If the p-field is set
|
||
|
|
to 1, the GRDLIN keyword will not be processed. If the p-field is set to -1,
|
||
|
|
the grid line record currently shown will be cleared. If the p-field is set
|
||
|
|
to something other than the defined values, then the default 0 will be used.</p>
|

|
<p>Grid
|
||
|
|
line support requires DBCS equipment. This equipment should have the capability
|
||
|
|
of calling Japanese DOS.</p>
|

<p>Option indicators are valid for this keyword.</p>
