5.3.3 GLOBAL WINDOW SETUP

The GP unit can display one Global Window and two Local Windows at any one
time. The Global Window is common to all the display screens. The Local
Window displays exclusively on the corresponding base screen. The GLOBAL
WINDOW SETUP is described here.
GLOBAL WINDOW
There are two options here: Use and Do Not Use. If you select Do Not Use,
ignore the items described below. Selecting Use enables these options.
GLOBAL WINDOW ACCESS
Use this feature to designate whether a value used is DIRECT or INDIRECT, i.e.
the REGISTRATION NO. and the LOCATION values. When set as Direct, the
REGISTRATION NO. and LOCATION selections are fixed to the values entered
here. When set to Indirect, the WINDOW REG. NO.'s word address, as prepared
in the System Area, is a variable. This means it can have the REGISTRATION
NO. written to it and, as a result, multiple window screens can be used as Global
windows. You can use this method to adjust the Global window position by
writing the X,Y coordinates to the SYSTEM AREA's LOCATION word ad-
dresses.
DATA FORMAT
Setup whether the REGISTRATION NO. and the LOCATION values are BIN or
BCD values. This field is related only to indirect values.
REGISTRATION NO. (1-256)
Enter the Window Screen Number used by the Global Window. This field is
enabled only when GLOBAL WINDOW ACCESS is set to direct.
Window Location (X and Y coordinates)
Enter the value used for the (Global WINDOW) LOCATION. This field is en-
abled only when GLOBAL WINDOW ACCESS is set to direct. This value desig-
nates the top-left corner of the screen registered in GLOBAL WINDOW SETUP.
If you install the GP vertically however, this value will designate the bottom-left
corner's coordinate.
