External resources are files represented by Data Structures
or Reports. To add external resources in a Program, you must specify
their logical and physical characteristics and the way they are to
be used in the Program.
Procedure
- Open the -CD Lines tab of a Program.
- Insert a CD line by clicking Add CD Line. The following selection box opens up (figure 1):

Report
In this selection box, you can check one or more Data Structures
or Reports, or both. If the Data Structure or Report you want to call:
- Is displayed in the selection box, click its corresponding check
box and click OK.
Note: By default, a Data
Structure is inserted as a sequential file with fixed-length records.
It contains all of the Data Structure records, with the Data Elements
in internal format, without the optional Data Elements.
- Does not exist yet, click New Data Structure or New
Report. In the creation wizard which opens up, enter the name and label of
the Report and click OK. The new instance is
then displayed in the selection list. If you select it and click OK,
it is called on a -CD Line.
- Complement the -CD line if necessary. To insert a:
- Data Structure in an existing Data Structure -CD line
used to specify a composite Data Structure. Select this -CD line on
the first level of the tree, or a Data Structure call line nested
under the -CD line (on the second level of the tree). Click Add
Data Structure. In the selection box
which opens up:
- Check that the instance you want to call in the Program and click OK.
- To call an instance which does not exist yet, click the New
Data Structure. In the creation wizard which opens up,
enter the name and label of
the Data Structure and click OK. The new Data
Structure is then displayed in the selection list. If you select it
and click OK, it is called in the selected
-CD Lines.
- Report in an existing Report -CD line in order to specify
a composite Report. Select this -CD line on the first level of the
tree, or a Report call line nested under the -CD line (on the second
level of the tree). Click Add Report. In the selection box which opens up:
- Check that the instance you want to call in the Program and click OK.
- Or, to call an instance which does not exist yet, click New
Report. In the creation wizard which opens up, enter the name and label of
the Report and click OK. The new Report is
then displayed in the selection list. If you select it and click OK,
it is called in the selected -CD Lines.
- Segment in a Data Structure already called in the Program,
select this Data Structure call line or a Segment call line and click Add
Segment. In the selection box which opens
up:
- Check that the instance you want to call in the Program and click OK.
- Or, to call an instance which does not exist yet, click New
Segment. In the creation wizard which opens up, enter
the name and label of
the Segment and click OK. The new Segment is
then displayed in the selection list. If you select it and click OK,
it is nested in the selected Data Structure call line.
What to do next
After the -CD Lines have been inserted, you can modify their
default characteristics in the sections which automatically open up,
depending on your selection:
- To change a Data Structure code in program, external
name, organization, describe its usage.
You must select a Data Structure CD line and modify the values displayed
in the -CD Line Definition (Data Structure) section.
Do not forget to click the More button to access
more specifications which are not displayed directly in the section.
- To specify whether all of the Data Structure Segments are to be
called in the CD line, you must select a Data Structure call line.
Then, you can modify the selection in the Data Structure
call section. From this section, you can also change the
called Data Structure and access the Data Structure tabs.
- To specify the Segment code in program,
you must select a Segment call line and enter this code in the Segment
call section. You can also access the Segment tabs
- To enter the characteristics of the Report called in the -CD Lines,
you must select a Report line. Then, you can modify the default values
