Description:

■ KEY ON

KEY

ON enables keystroke trapping for a function key specified by keynumber.

(Refer to Appendix E, "Key Number Assignment on the Keyboard.")

• Between every execution of statements, the Interpreter checks whether a function

key specified by the

KEY ON statement is pressed or not. If the key is pressed,

the Interpreter transfers control to the event-handling routine defined by an

KEY...GOSUB

statement before the KEY ON statement.

• If a function key which has been assigned a null string by the

KEY statement is

specified by the

KEY ON statement, the keystroke trap takes place.

• If you specify a function key which has been defined as the LCD backlight func-

tion on/off key, trigger switch, shift key, or battery voltage display key by using the

KEY ON statement, then no keystroke trap takes place.

• Keystroke trapping has priority over the

INKEY$ function.

I/O statement

KEY ON and KEY OFF

Enables or disables keystroke trapping for a specified function key.
