Modify the Client PrADs

For each of the client component PrADs, complete the following steps.

Follow these steps:

1. Select all lines of logic in the PrAD, except for initial statements that move imports to exports.
2. Delete the lines of logic.
3. Add logic that sets an exit state of FLOW_TO_SERVER and then escapes.

   You want the current command to get passed to the server procedure step. The server procedure step already has a CASE OF COMMAND structure to handle the command.

4. Increase the cardinality of the repeating group views.

   GUI client PrADs can handle more data than PrADs for terminal-based screens. A terminal-based screen is limited to 25 lines. Windows and dialogs can have numerous scrolling list boxes, drop down lists, and so on.
