can someone show me how to use this and what it does with pic will help alot.

That function only changes a number into its binary representation. Example: BIN(4) gives "100" BIN(4,4) gives "0100"

where does it show binary..when i hit run?

That's a value returned from the function(A String). It's up to you to decide what to do with that. If you want to see the result on the console, then type: ? bin$(variable)

I saw that you want to make a encryptation algorithm. I have bad news for you: bin$() won't help you too much because it return a string. You need to learn how use bitwise operators(>>,<<,and,or,xor) to handle them as a binary.

ok thx man that helped and i got it to show the binary code of a # by puting print b4 it
