Syntax

CALL GASK ('MAXDISP', units, x-dim, y-dim, x-pixels, y-pixels, return-code-variable);

Description

The GASK('MAXDISP', . . . ) routine returns the dimensions of the maximum display area for the device. This routine is useful when you need to know the maximum display area in order to determine the aspect ratio or to scale a graph.

There is a difference between the maximum display size returned when the operating state is not SGOP and when it is SGOP. The full addressable display area is returned when the operating state is not SGOP, and the display area minus room for titles and footnotes is returned when the operating state is SGOP.
