Are you aware that each variable will consume 16 bytes of RAM? i think it is a bit too much

Can you describe a little more your application.

If you are using C, what compiler are you using?, what derivative of 8051 are you using?, did you check the forum if there is a threat similar to yours?

I don't know if a C compiler can do what you ask since i haven't worked with C only ASM, but i can say that you are posting a gimme code ask, not many will give away code if it seems you even bothered in searching in this forum
