Diagnostic messages—If an error is detected in a CA 2E generated program, a message is sent to the program’s message queue. All interactive programs have a message subfile to show the pending messages on the program’s message queue. This message handling technique makes full use of the sophisticated message handling capabilities of i OS, allowing both second level text and substitution variables. It also ensures that applications can be translated easily into other national languages.
Highlighting of errors—Any field found to be in error is highlighted in reverse image. The cursor is positioned at the first of these fields.
On-line Help text—All the interactive programs generated by CA 2E include processing to call a program to display Help text when the Help key or F1 is pressed.
Print key—The print key is enabled to allow panel prints. The name of the print key spool file can be controlled with the YPKYVNM model value.
Selection columns—Subfiles that allow selection of individual items always have the selection column on the left.
Function key usage—Function key usage is standardized to follow CUA standards: for example, F3 is exit.
For more information on function key usage, see Function Key Defaults in the chapter "Setting Default Options for Your Functions."
Positioning facilities—When appropriate, programs that use subfiles have a positioning field on the subfile control record that you can use to control which records are shown in the subfile.
