User key to toggle to and from RPN

[ekeppel]

I use a slightly modified version of the Entry Mode Switcher (found elsewhere in the forums).

KEY K_View()
BEGIN
Entry:=(Entry+1) MOD 3;
STARTVIEW(-1,1);
TEXTOUT_P(STRINGFROMID(1903+Entry),G0,2,207,2,RGB(255,0,0));
//FREEZE;
WAIT(.5);
END;

To change modes, just hit Shift - Help - View.


EDIT:
If all you want is a most basic toggle between RPN and Textbook, without feedback on the current mode and skipping Algebraic, you can use this (also not my work, but found here on the forums):

KEY K_View()
BEGIN
IF Entry == 0
THEN Entry:=2
ELSE Entry:=0;
END;
END;

Of course you can replace K_View in these examples with whatever user key you like. Hopefully one of these does what you are looking for. :-)
