GET GET variable list
The GET statement is a way to get data from the keyboard one
character at a time. When the GET is executed, the character that
was typed is received, it no character was typed, then a null (empty)
character is returned, and the program continues without waiting for
a key. There is no need to hit the RETURN key, and in fact the
RETURN key can be received with a GET.
The word GET is followed by a variable name, usually a string variable.
If a numeric were used and any key other than a number was hit, the
program would stop with an error message. The GET statement may
also be put into a loop, checking for an empty result, which waits for
a key to be struck to continue. The GETKEY statement could also
be used in this case. This command can only be executed within
a program.

EXAMPLE:
10GETA$:IFA$
"A"THEN 10
This line waits for the
A key to be pressed
to continue.
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. This lets it be used easily to wait for a single char
acter to be typed.
This command can only be executed within a program.
EXAMPLE:
10 GETKEY A$
This line waits for
a key to be struck.
Typing any key
will continue the
program.
GET# file number.variable list
Used with a previously OPENed device or file to input one character at
a time. Otherwise, it works like the GET statement. This command can
only be executed within a program.
