Defining the data segment

Use the Definition of the Selected Data Segment pane to modify existing or define new data segments. Modify a data segment definition by editing, deleting, or adding new elements to the segment.

The list box lists the data elements and composite data structures included in the data segment.

  1. Click the segment name in the Defined Data Segments pane. The selected segment definition displays in the Definition of the Selected Data Segment pane.
  2. Designate where to place the new data element or composite by clicking the Add/Paste New Elements arrow and making a selection. For example, to add an element or composite after or before a particular element or composite on the list:
    1. Click the element where the insertion is to be made.
    2. Click After Selected Element(s) or Before Selected Element(s).
  3. Click the Add tool that is located below the Definition list.
  4. If necessary, then use the editing tools by clicking the appropriate tool that is located below the Definition of the Selected Data Segment list box.
  5. Specify if the segment’s elements are required or conditional:
    • Mandatory specifies the element’s inclusion is required.
    • Conditional specifies the element’s inclusion is conditional.
