GETTEXTWINDOW

Graphics Subroutine: Finds the boundaries of the current text window.

Module: USE DFLIB

Syntax

CALL GETTEXTWINDOW (r1, c1, r2, c2)

r1, c1
(Output) INTEGER(2). Row and column coordinates for upper-left corner of the text window.

r2, c2
(Output) INTEGER(2). Row and column coordinates for lower-right corner of the text window.

Output from OUTTEXT and WRITE is limited to the text window. By default, this is the entire window, unless the text window is redefined by SETTEXTWINDOW.

The window defined by SETTEXTWINDOW has no effect on output from OUTGTEXT.
