Rational Programming Patterns

Adding external resources to a Program

External resources are files that are 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

  1. Open the -CD Lines tab of a Program.
  2. Insert a CD line by clicking Add CD Line. The following selection box opens up (see figure 1):
    Figure 1. Selection of a Data Structure or a Report
    Selection of a Data Structure or a Report, or both.
    In this selection box, you can check one or more Data Structures or Reports, or both. If a list is large, you can reduce it by entering a string that is used as filter. The filtering is performed on the code or on the label of the instance. Then, the list displays only the instances whose code or label contains the string you entered.
    • 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.
    • If the Data Structure or Report that you want to call does not exist yet, click New Data Structure or New Report. In the creation wizard, 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.
  3. Complement the -CD line if necessary.
    Note: The possible actions with the buttons are also available in the contextual menu of the tree.
    1. To insert a Data Structure in an existing Data Structure -CD line used to specify a composite Data Structure, select this -CD line, or a Data Structure call line that is nested under the -CD line. Click Add Data Structure. :

      In the selection box that opens, select the instance that you want to call in the Program and click OK.

      If the instance does not exist yet, click the New Data Structure. In the creation wizard, 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.

    2. To insert a Report in an existing Report -CD line to specify a composite Report, select this -CD line on the first level of the tree, or a Report call line that is nested under the -CD line (on the second level of the tree). Click Add Report.

      In the selection box that opens, select the instance that you want to call in the Program and click OK.

      If the instance does not exist yet, click the New Report. In the creation wizard, 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.

    3. To insert a 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 that opens, select the instance that you want to call in the Program and click OK.

      If the instance does not exist yet, click the New Segment. In the creation wizard that opens, 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 that automatically open up, depending on your selection:
