What if i want to calculate like R = a+b+c and later
PRINT ({R});
Do I have to define R in local or can i just go like this
LOCAL a,b,c,d;
INPUT({{a,[0]},{b,[0]},{c,[0]},{d,[2]}},"Input test", {"Input σ₁²","Input σ₂²","Input σ₁₂","Input F(α,2,f)"});

R= a+b+c;
PRINT({R});

Will this work ?

Try it???

It doesn't work, it seems that you have to define all of your variables at the start. This is not very practical. Is there a way that I can define new variables as I go. I'm not sure how many i will need.
Now I see why most people decide for other brands of calculators that are even slower. You dont have to be a programmer to write a simple program.
