Quote:EXIT will also return from the current program but it can only exit one program at a time.

I'm not sure to understand your point. Perhaps I missed or misunderstand something. I thought that EXIT was something like BREAK in PPL, and my suggestion for RETURN was something like the RETURN in PPL.
For me EXIT dont return from the current program but exit the current loop (Or perhaps behind the scene a loop is a program in newRPL ?).
The idea of RETURN is different : stop the program (the subprogram) here and returns the stack "as it is" :

Exemple

Code:

«
 1 9 FOR 'a'
  1 9 FOR 'b'
   IF  a b + 4 == THEN a b RETURN END
  NEXT
 NEXT
»

-> 1 3

'a' loop is just executed once
'b' loop 3 times

But with EXIT

Code:

«
 1 9 FOR 'a'
  1 9 FOR 'b'
   IF  a b 4 + == THEN a b EXIT END
  NEXT
 NEXT
»

-> 1 3 2 2 3 1

The inner loop stops each time the condtion is true
The outer loop is executed 10 times
