just curious...

I dont like the way CASE is implemented in the Prime.
In langage like Pascal it's easier to understand and read, but perhaps less flexible.

Code:

Case x Of
 1 : do something;
 2 : do someting else ;
 3 : etc;
 Default; ...
End;

or

Code:

Case x Of
 1,2,9: do domething if x=1 ou or x=2 or x=9;
 3..7 : do someting else if x between 3 and 7 ;
 8    : etc;
 Default;
End;

By the way, the CASE instruction is interesting on the PRIME as Didier Lachieze wrote and avoid a succession of imbricated IF THEN ELSE. And if understand well your exemple with RETURN only works if you have a subroutine dedicated to the test cases.
