Hi all, My code is based on C and I have a lot of cases where I assign a value to a variable. Is it more efficiency to just place the value or first to check if the variable already has this value? I made two identical sample codes where in one code I had only an assignment of a value and in the other one I had verification first. I see that the CODE area in the second sample was bigger then the first one. If CODE area is smaller, it's not mean that all code is more efficiency. Any ideas? Ruven
