Description

The DEFINE BAR <expN> defines a single option in a pre-defined Xbase style pop-up <expC1> menu. If you have used the PROMPT FIELD, PROMPT FILES, or the PROMPT STRUCTURE options in your pop-up menu definition, the DEFINE BAR command is unnecessary. The command SET COMPATIBLE should be set ON when using Xbase style menus. The PROMPT <expC2> defines the text that will appear in the menu item.

KEY <key>, [<expC3>]

The KEY <key>, [<expC3>] is provided for Xbase language compatibility only. The value <key> is the key combination defined to access the particular option. The <expC> defines the label displayed on the option bar.

MESSAGE <expC4>

The optional MESSAGE <expC4> displays a message centered on the last line of the screen when the bar is selected by the user.

SKIP FOR [<expL>]

The optional SKIP command allows the display of a defined bar but does not allow selection of that bar. The optional SKIP FOR <expL> allows selection of a defined bar only when the specified condition is true.

Example

define popup popup_4;
  from 1,26
define bar 1 of popup_4;
  prompt "\<Bar 1"
define bar 2 of popup_4;
  prompt "B\<ar 2"
define bar 3 of popup_4;
  prompt "Ba\<r 3"
activate popup popup_4
