How the heck do I Iterate and Emulate?

I've got a HP-50G, but people have been humming about the Prime for a little while now. I installed the emulator, and I have upgraded to the 8151 version. I tried a really simple program in the HP emulator:

Code:


EXPORT ITTST()
BEGIN
LOCAL X;
PRINT("X is "+X);
ITERATE(X^2,X,2,3);
PRINT("X is now "+X);
END;

All I get as output is "X is 0" (understandable) and "X is now 0" (which is not). Clearly I'm doing something completely wrong, as I typed the ITERATE example in from the manual, yet I'm not getting the same results as the manual. I also tried it in the Home screen, ITERATE worked fine there. So, where am I going wrong?

ITERATE doesn't change the value of your local variable X.
You should do:
X:=ITERATE(X^2,X,2,3);

Ahh, that would explain that. So it's a bit more like PASCAL than I previously thought. Thank you.
