User key assignment

[rlinden12]

Hi all...!

Whenever I try to use an expression "KEY K_On()" (or any other key assignment) in Cristóbal De Jesús' program "A Simple Entry Mode Switcher" I receive an error when I check the code.

// Cycles over entry mode options.
KEY K_On()
BEGIN
LOCAL an:={"Textbook","Algebraic","RPN"};
Entry:=(Entry+1) MOD 3;

STARTVIEW(-1,1); // Refresh Home view BEFORE tagging...

TEXTOUT_P(an(Entry+1),G0,2,207,2,RGB(255,0,0));
FREEZE; // the mean part!
END;

The HP Prime I have is the latest one and has been updated to the latest ROM...

Any thoughts?

Thanks,

Rob
