-CS Lines tab in a Screen editor

This tab is used to indicate how to access Segments in the validation, update and display. You specify here the physical attributes and access conditions of each Segment (standard file or database type, keys, etc.), and the use characteristics and logical characteristics of the Data elements called in these Segments.

General characteristics

For each Segment, the following attributes are specified:
The number of Segment description lines called in this screen is limited to 100 per category. Segments having the same Data Structure codes must have the same organizations, the same types of description, and, with a V-type organization, the same external names. For a D-type organization, Segments having the same Data Structure codes are generated in REDEFINES.
The processing of data external to the Screen is determined by the call of Segments and, for each of them, by the specification of its physical characteristics (type of organization...) and type of use (read, update...).

Description of the tab

The -CS tab consists of three parts:

List of Segments (Persistency objects)

On the left part of the tab, you find a structured list of Segments called in the Screen. On the higher branches, you have the Segments call lines (Segments that support persistent objects), and on the lower branches are listed the persistency objects represented by Data elements that are grouped under the same physical storage objects. They are represented by theData elements call lines.

You can complete and reorganize the list via the choices available in the popup menu (copy, paste, revert, do, undo) and buttons (Add Segment call, Add Data element call, Remove, Up, down).

Buttons

The buttons are used to organize the list.
Add Segment call
Clicking in list and then on the Add Segment call button creates a new line in the list that corresponds to a new Segment call. The code and description of the new Segment is to be completed in the Segment call section in the right part of the tab.
Add Data element call
Clicking on a line and then on the Add Data element call button opens a selection box in which you can select a Data element code or define a new one. As a result, a new line is created under the one you have selected in the list. The information related to the Data element call are to be entered in the corresponding Data element call section in the right part of the tab.
Remove
Clicking a line in the list and then this button, removes the selection from the list. If the selected line is a branch regrouping several lines, they are all removed from the tree.
The Up and Down buttons
Use these buttons to move a selected line in the list or a selected branch in the tree.

Segment call/Data element call sections

The Segment call section and Data element call section only display when you select respectively a Segment and a Data element in the list of -CS lines otherwise they are shaded.
