Programmatically changing Entry mode crashes iOS Pro App

[pinkman]

Hi,
I created the following function to automatically switch between Textbook and RPN modes:

Code:


KEY K_Menu()
BEGIN
 LOCAL s := {"Textbook", "Algebraic", "RPN"};
 Entry := ABS(Entry-2);
 TEXTOUT_P(s(Entry+1), 15, 9, 1, RGB(255,180,80));
 WAIT(1);
 RETURN -1; // see edit comment below
END;

It works fine on my physical HP Prime, but on the iOS App it crashes every 2 switches.
Am I doing something wrong?

Thanks,
Thibault

PS: yes I know, in case of algebraic mode it stays in this mode, but I never use it.

[edit] Added « RETURN -1; » in the code, according to Cyrille’s suggestion (just in case you copy it directly to your Prime without reading the whole thread)
