= INKEY$
The INKEY' (or
INKEY$) capture a single character typed by the user
without having to press enter. In other words, the program is “listening”
to the keyboard and, as soon as a key is pressed, “captures” it and
stores it in a variable.
Unlike the
INPUT command, which requires the user to press enter after
typing,
INKEY reads the character as soon as it is pressed. If no key
has been pressed,
INKEY$ returns an empty string (“”). The captured
character is stored in a string variable.
It is used to create interactive games where the user can control the
character or objects by pressing specific keys, to create text menus
where the user can select an option by pressing a letter or number
or to create programs that respond to external events, such as
pressing a key to start or stop an action.
The
INKEY$'' only reads one character at a time. To read a complete
string, you must use other commands or techniques. The command
does not usually display the pressed character on the screen.
IF INKEY$ = "A" THEN PRINT "A has been pressed!" ENDIF
