Simple programming help with the Prime

Code:

EXPORT ADD(X,Y)
BEGIN
  RETURN X+Y;
END;

and would be invoked as

Code:

ADD(2)

Does that make sense?

It seems there has been some changes with the latest firmware update because now in RPN mode you don't need anymore to specify the number of arguments when calling a User program, with your program example:

Code:

2 ENTER 3 ADD() ENTER

returns 5.

However in algebraic mode you still need to call your program with:

Code:

ADD(2,3) ENTER

to get 5.
