On CASIOs the simplest SIGN(var) function is (var>0)-(var<0). Maybe it's works on 3650P and similar models. I have checked on my 4000P (seems same as FC models) this causes Syntax error.

Yeah, I don't think Casio changed the relational/comparison operators to work like actual mathematical functions until somewhere around the fx-9750G/cfx-9850G. Prior to that, you could only use them in conjunction with the 'if/then' arrow.
