OpenGraphic( TagName:=Expression )

Parameters

ParameterTypeDescription
TagName ANY_STRING The name of the Graphic Page Tag to open. The name can be the full name of the tag or a relative tag name.

The OpenGraphic function opens a Graphic Page Tag. The exact behaviour varies according to the context:

If the OpenGraphic call is made from a Graphic Page Tag you can use a relative tag name for the TagName parameter. A relative tag name indicates a name relative to the host document. For more information on how relative names are resolved see Tag References.

A program or script will not execute any statements after the OpenGraphic call.

The OpenGraphic call is logically equivalent to:

OpenTagFile( TagName, 'fhgrp' );

Return Value

None.

Examples

Displays the graphic page 'Diagrams.PumpControl':

OpenGraphic( "Diagrams.PumpControl" );
