I am anything else but a math geek so I am stunned by the following:
C<>7 ASCII
x(0)=0 x(n+1)=C(n) mod(Y/17)
y(0)=0 y(n+1)=y(n)+(C(n) mod(X/80))+1
What kind of calculation or equation is that? I am especially confused by the case change of x and y on the left to upper case on the right. Does this have a special meaning or is it just a mistake?
