SHOWPAGE

The SHOWPAGE action is used to switch between display pages. Using SHOWPAGE you can allow the end-user to browse through your program screens.

An Action may use a Value and an Address
Value: empty.
Address: address of the page to show, e.g. $Display Page.

Value

Normally leave empty.

Write LAST to return to the page that was addressed in the previous call to SHOWPAGE (available since 1.34.1).

Write TOP to bring the application window to the top of all windows (available since 1.34.0).

Address

Address of a page. If no address, or a wrong address is specified, a warning pops up as soon as the action is performed.

Synchronous or asynchronous

This action is performed asynchronously with data processing. If an action is asynchronous, it is performed only after all synchronous actions in a sequence have been called. A synchronous action is performed immediately.
