A simple Entry Mode Switcher...

[Cristóbal De Jesús]

... with visual feedback. Probably the simplest program so far, it's a key definition.

Code:

// Cycles over entry mode options. 
KEY K_On() 
BEGIN 
LOCAL an:={"Textbook","Algebraic","RPN"}; 
Entry:=(Entry+1)MOD3; 

STARTVIEW(-8,1); // Out to ANY AVAILABLE view... 
STARTVIEW(-1,1); // ... and back in, to refresh 

TEXTOUT_P(an(Entry+1),G0,2,207,2,RGB(255,0,0)); 
END;
