Your COBOL system provides some support for ACUCOBOL-GT windowing syntax that enables you to draw lines and boxes on the terminal
screen, and create virtual terminal windows on a physical terminal. All ACCEPT and DISPLAY statements then act within the
current window (except for ACCEPT format 1, 2, or 3 statements, DISPLAY format 1 statements, and DISPLAY WINDOW/LINE/BOX statements).
The syntax also enables underlying displays to be kept and restored.
Note: This functionality is supported in native COBOL only.
