Towards custom RPN mode: How to Completely override application?

[xset]

I need completely override application and restart it after Shift-Off, but it ignores Plot function and shows Plot view of parent application (from which i inherit main).

Calculator ignores Plot function at all in number of condition.

EXPORT MyApp()
BEGIN
STARTVIEW(1,1);
END;

START()
BEGIN
STARTVIEW(1,1);
END;

Plot()
BEGIN
RECT();
TEXTOUT_P("Begin",10,10);
WHILE 1 DO END;
END;

This is strange "inheritance" if we can't control original application.

Many thanks

I have found at least we can intercept ON key preventing unforeseen exit form the app. But it will not start automatically after Shift-Off -> On ???
