How to Create Displays

CA SYSVIEW lets users create their own CA SYSVIEW command displays. The display can be simple rows of text data, or can be formatted using extended attributes.

The user display supports the following:

• Extended attributes
• Help
• Line commands
• Selection
• Sorting

To create your displays, do the following:

1. Use REXX to build your new user command.
2. Use the control statement to let the REXX EXEC embed statements to define a title, info lines, header lines, link fields, and so on.
3. Use the data queued to the REXX stack to create the display.
4. Use the RXDISP command to invoke a REXX EXEC and display any output returned on the stack on a CA SYSVIEW screen.

Example: REXX EXEC Samples

The REXXLIB data set, SYSVIEW.CNM4BREX, contains the following REXX EXEC samples:

FILELIST

Provides a sample REXX EXEC to create a display that contains a directory listing of multiple data sets.

LOAN

Provides a sample REXX EXEC to calculate loan. payments.
