This standard runtime function displays the help message, if any, that you defined for a field/control. It allows you to display, rather than re-create, existing help messages in situations other than those involving user input. (Help messages are displayed automatically when the Help key is pressed during user input.)
SHOW FIELD HELP displays the message, waits for the operator to press any key, erases the message, and then returns control to the application program.
The application program must set the name of the field/control for which the help message is to be displayed in RMP--FIELD-NAME. No occurrence number is required, even for fields/controls with multiple occurrences, as the help message applies to each occurrence.
