<div class="section"><div class="p">The format of the keyword is: <pre>GDF(library-name | &library-name-field

</div>
|

|
|
<p>The graph-file
|
||
|
|
and graph-member parameters identify the chart to be printed. Both are required
|
||
|
|
parameters.</p>
|
||
|
|
<p>Use the optional library-name parameter to further qualify
|
||
|
|
the graphic data file and member. If you do not specify the library-name parameter,
|
||
|
|
*LIBL is used to search for the graphic data file at print time.</p>
|
||
|
|
<p>You
|
||
|
|
can specify the library-name, graph-file, graph-member, position-down, position-across,
|
||
|
|
graph-depth, graph-width, and graph-rotation parameters as constants, program-to-system
|
||
|
|
fields, or a combination of both, as shown in the following examples:</p>
|
||
|
|
<ul><li>[library-name/]graph-file graph-member...</li>
|
||
|
|
<li>[library-name/]&field1 graph-member...</li>

<li>[&field2/]graph-file &field3...</li>
|
||
|
|
<li>[&field4/]&field5 &field6...</li>
|
||
|
|
</ul>
|
||
|
|
<p>When you specify library-name, graph-file, or graph-member parameters
|
||
|
|
as program-to-system fields, the fields must exist in the same record format
|
||
|
|
as the GDF keyword. They must be defined as length 10, data type A (character),
|
||
|
|
and usage P (program-to-system).</p>
|
||
|
|
<p>When you specify the position-down,
|
||
|
|
position-across, graphic-depth, or graphic-width parameters as program-to-system
|
||
|
|
fields, the fields must be defined as length 5 with 3 decimal positions, data
|
||
|
|
type S, and usage P. When you specify the graphic-rotation parameter as a
|
||
|
|
program-to-system field, the field must be defined as having a length of 3
|
||
|
|
with zero decimal positions.</p>
|
||
|
|
<p>The position-down parameter is required
|
||
|
|
and defines the vertical starting point of the chart relative to the margins
|
||
|
|
specified on the FRONTMGN or BACKMGN parameter on the CRTPRTF command. Valid
|
||
|
|
values are 0 to 57.790 cm (0 to 22.750 in.).</p>
|
||
|
|
<p>The position-across parameter
|
||
|
|
is required and defines the horizontal starting point of the chart relative
|
||
|
|
to the margins specified on the FRONTMGN or BACKMGN parameter on the CRTPRTF
|
||
|
|
command. Valid values are 0 to 57.790 cm (0 to 22.750 in.).</p>
|
||
|
|
<p>The graph-depth
|
||
|
|
parameter is required and defines the depth of the chart. The chart is scaled
|
||
|
|
to fit within the area specified by the graph-depth parameter. Valid values
|
||
|
|
are 0.001 to 57.790 cm (0.001 to 22.750 in.).</p>
|
||
|
|
<p>The graph-width parameter
|
||
|
|
is required and defines the width of the chart. The chart is scaled to fit
|
||
|
|
within the area specified by the graph-width parameter. Valid values are 0.001
|
||
|
|
to 57.790 cm (0.001 to 22.750 in.).</p>

see <cite>Graphics object content architecture reference, SC41-6804</cite>.</div>
|

|
<p>You can create graphics data format files with the <span class="keyword">Business Graphics Utility</span> (BGU) licensed program or the

Graphical Data Display Manager (GDDM<sup>®</sup>), which is a function of the <span class="keyword"><font color="Purple">i5/OS™</font></span> system.
|

|
|
As soon as the objects exist, you can print them with the DDS graphics data
|
||
|
|
format file (GDF) keyword to determine the location (library), identity (file
|
||
|
|
and member name), position (down and across with a possibility of three decimal
|
||
|
|
positions, for example, 1.001), size (width and depth), and rotation of the
|
||
|
|
object.</p>
|
||
|
|
<p>You can use the Display Graphics Data File (DSPGDF)
|
||
|
|
command to view the objects on a display station. Viewing the object before
|
||
|
|
using the DDS GDF keyword to print it can help with selecting the position
|
||
|
|
values required on the GDF keyword.</p>
|
||
|
|
<p>Specify DEVTYPE(*AFPDS) on the CRTPRTF
|
||
|
|
command when GDF is specified in the file. If DEVTYPE is changed to anything
|
||
|
|
other than *AFPDS, the keyword is ignored and a warning message is issued
|

|
|
at print time.</p>
|
||
|
|
<p>When GDF is specified on a record format, all fields
|

|
|
within the record format must be positioned using the POSITION keyword.</p>
|

|
|
<p>An
|
||
|
|
error message is issued if a constant field is specified in a record format
|

|

where the GDF keyword is also specified.</p>

<p>You can specify this keyword

multiple times on a record.</p>
