The Display Screen
The default system font for the PT40 is a 5x7 (width x height in pixels) font
based on the Codepage 850 Western European character set. This size font
allows the PT40's LCD display screen to show 6 lines of text with up to 16
characters on each line when using only the default system font.
Actual vs. Virtual Display
The Falcon PT40's actual display screen is a window to a larger display area
called the virtual display (refer to
Figure 1-3
). Most applications you will use
will fit into the actual display. However, applications can sometimes contain
data longer than the default 6 line x 16 character view of the actual display.
