Hi I need prime factorization program for Casio FC-200. I found this on internet:

Lbl 0:"N="?➝A:Goto 2:
Lbl 1:2◢
A÷2➝A:A=1⇒Goto 7:
Lbl 2:MOD(A,2)=0⇒Goto 1:3➝B:
Lbl 3:√A+1➝C:
Lbl_4:B≥C⇒Goto 6:
MOD(A,B)=0⇒Goto 5:
B+2➝B:Goto 4:
Lbl 5:B◢
A÷B➝A:Goto 3:
Lbl 6:A◢
Lbl 7:"END":Goto 0

But i don't have ≥ and MOD function.

I replaced the MOD function using this pattern: MOD(A, B ) = A - B*Int(A/B), but i don't know how i should repleace ≥ into two separate conditional statements (>, =).

Program also have to contain less than 128 steps because that's the maximum capacity of my calculator.

Instead of A≥B you can use Not (A<B )
