Getting Started
NUMERIC KEYPAD
A group of 15 keys at the right-hand side of
the keyboard. It is arranged much like a
standard calculator's keypad and is
call~d
"numeric keypad." It includes not only the
numbers 0 through 9, the decimal point, the
plus
(+)
and minus (-) keys, but also cursor
movement keys, PGUP, PGDN, HOME,
NlJM LOCK, SCROLL LOCK, BREAK,
END, INS, DEL, etc.
Note that some keys like SCROLL LOCK,
PGUP, and PGDN are not used by GWBASIC,
but they may be assigned meanings
within a program.
Number Lock State
You cali press the NUM LOCK key to shift
the numeric keypad into upper-case. This
mode provides the numbers 0 through 9 and
the decimal point. (Holding down one of the
two SHIFT keys produces the corresponding
lower-case keys in this mode.) To return to
lower-case, press NUM LOCK once again.
