GSET^%ZISS: Set Up Graphic Variables

Reference Type: Supported, Category: Device Handler, Integration Agreement: 10088

Description

This API is used for screen management. It sets up graphic variables for screen handling. Graphics on/off is a toggle that remaps characters for use as graphics. Not all terminals need remapping (like DataTree consoles, for example) since they already have the high range of ASCII codes.

Format

  GSET^%ZISS

Make sure to perform the following steps before calling this API:

  1. NEW all of the following variables.
