Rational Programming Patterns for System z

Screen Overview tab

The Overview tab of a Screen displays the label, in a read/write mode. It also displays the instance name, type of COBOL and map to generate, Program external name, Map external name and transaction code in a read-only mode. It provides access to the other tabs of the instance.

Description of the tab

Three sections are not tabs themselves. They are displayed in the Overview tab only: Alerts and Action Items, General information, and Generation parameters definition (on some entities).

All the other sections provide links to the corresponding editor tabs.

If information is displayed in each section, you can:
  • Click it if it is displayed as a link. You automatically switch to where the information has been specified.
  • Or click the More button to switch to the corresponding tab.

If no information is displayed in the section, click the arrows located in front of the section name. It gives you access to the More button. Click it to access the corresponding tab.

The sections of the tab

Alerts and Action Items
Any problem related to the current instance (for example: if the instance calls another instance which has been deleted...) is displayed here as a link. If you click this link, you automatically switch to the Problems view, where the line corresponding to the error is highlighted. The error is clearly explained and you can correct it.
General information displays the following fields:
Work context
The work context is the project from which you have opened the editor of the current instance. This project constitutes the starting point for the resolution of the dynamic links and references between the instances contained in the various projects of the location. The projects hierarchy declared in the design build path is explored in an upward direction.

If you click Hierarchy, you can see a partial view of the design build path. In this view, the project which constitutes the work context is the lowest project of the hierarchy.

More information can be found in the following topics: The work context and The design build path.

Name
The instance name is displayed in read-only mode. It is entered when the instance is created and cannot be modified later.
Label
Enter the label, which identifies the new instance. It constitutes a search criterion for a subsequent search.
Generation parameters definition
Generation parameters are specified in Libraries. These parameters are related to the adaptation to the operating system in use.

So the current instance is associated with the generation parameters indicated in the Library displayed here. You can click Change to select another Library.

The other sections of the tab display, in a read-only mode, the information entered in the corresponding tabs:
  • The Definition section displays the type of COBOL and map to generate, the Program external name, Map external name and transaction code entered on the Definition tab. It also shows the Generated skeleton language, selected in the Definition tab of the Library where the Screen is defined.
  • The -CE Lines section displays the fields which constitute the Screen.
  • The -CS Lines section displays how Segments are accessed in the validation, update, and display processing associated with the Screen.
  • The -CP Lines section displays the Macro calls in the Screen.
  • The -G Lines section displays the comments, generation options, generation elements, and error messages/help messages specified on the Screen.
  • The Keywords section displays the keywords assigned to the Screen.
Note: To indicate internal resources, you must specify micropatterns directly in the generated COBOL file.
