4GL choice sections

You use choice sections to program actions that you want to be executed when standard commands or form commands are activated or ended. Choice sections consist of a main section and a subsection. The main section specifies the standard command or form command for which the actions must be executed. The subsections specify when the actions must be executed.

Main section

choice.<standard command>:

The subsections associated with this main section are executed for the specified command. You can enable standard commands and specify form commands from the session Sessions(ttadv2500m000). A list of standard commands appears at the end of this help topic. For form commands, the session, menu or function name is used.

Subsections

before.choice:

The actions programmed in this subsection are executed immediately before the specified command is executed. You can use this subsection, for example, to test data before the command process continues. You can use the choice.again() function to stop the command.

on.choice:

The actions programmed in this subsection are executed when the specified command is activated. These actions are executed instead of the standard action associated with the command. This subsection is not always available. For details, see the list at the end of this help topic.

after.choice:

The actions programmed in this subsection are executed immediately after the specified command has been executed. This subsection is not available for the end.program and abort.program commands.

Example

 choice.first.view:      | standard command
 after.choice:
    execute(first.set)


 choice.ttadv2111m000:      | form command
 before.choice:
    export_var = "some value"

User Notes

The choice.sessionnumber: |* Form Command Section does not work, as found in Baan V.

Try instead:

choice.zoom:

This works on any session declared as a Session Zoom Form Command.
