GETKEY
—Receive buffered input data from the keyboard, one character at a
time and wait for a key to be pressed
GETKEY variable list
The GETKEY statement is very similar to the GET statement. Unlike
the GET statement, GETKEY waits for the user to type a character
on the keyboard if the keyboard buffer is empty. This lets the com
puter wait for a single character to be typed. This statement can be
executed only within a program.
EXAMPLE:
10 GETKEY A$
This line waits for a key to be pressed. Typing any key continues the
program.
10 GETKEY A$,B$,C$
This line waits for three alphanumeric characters to be entered from
the keyboard.

ment can be executed only within a program.
