OPENPAGE function
Displays a page name in new window.
Syntax
OPENPAGE("pagename")
Remarks
If a window is already displaying the page whose name is pagename, that window becomes active. If the pagename does not exist, or if Microsoft Visio is acting as an in-place server, the OPENPAGE function has no effect.
In earlier versions of Visio, this function appears as _OPENPAGE. Visio versions 4.0 and greater accept either style.
