Rational Developer for System z, Version 7.6

Screen -CE Lines tab

The purpose of this tab is to identify the fields which constitute the Screen. Each field has a position and a length. Some fields may contain data.

The elements which constitute the Screen layout are presented here in a tree and may be grouped inside three categories (top, repettive and bottom categories).

There are two major types of fields in a Screen:
  • Fields with fixed contents. These are generally labels, which are directly associated with variable fields and usually specify the contents of that field.
  • Fields with variable contents, which are either unprotected (input fields) or protected (display fields). These correspond to Data Elements described and processed in the program associated with the Screen layout.

You can also call an existing Screen in order to integrate its description into the current Screen.

The -CE Lines tab looks like this:

Screen -CE Lines

It is constituted of three different parts:
  • On the left, a tree which displays all the elements which constitute the Screen:
    • Fields, which can be protected, variable, or protected and received (field icon).

      Each field call line contains one or more nested lines which display the information specified in the additional controls for the selected field section (Additional controls for the selected field icon). Click on the + symbol located at the beginning of the field call line to see it. Each nested line shows, in their display order in the section, the values selected for these additional controls (the one-character values which correspond to the VA Pac choices, displayed in the first position of the items in the dropdown lists). Dashes separate each value. If the default value (which corresponds to a blank value in VA Pac) has been selected for a control, a blank is displayed in the line.

    • Labels, which can be fixed labels, Data Element labels, or Screen titles (Label icon).
    • Screen call (Screen call icon).

    Each call line displays the type and name of the element.

    These elements may belong to one of the three categories (Category icon). Each category can be defined only once in a given Screen:
    • The heading of the Screen (Screen-top category).
    • The repetitive section of the Screen (repetitive category),
    • The bottom of the Screen (Screen-bottom category).

    All the elements called before the repetitive category implicitly belong to the top category, even if the category line is not displayed. All the elements called after a category line belong to this category.

  • In the center part, buttons which enable you to add fields to your Screen, remove existing ones or move them up/down.
  • On the right, sections which open up depending on your selection in the left area. If you select a:
    • Label line, the Label Definition section opens up.
    • Category line, the Category Definition section opens up.
    • Screen call line, the Screen Call Definition section opens up.
    • Field line, the Field Definition section opens up.
    • Line nested inside a field line, the Additional controls for the selected field section opens up.
