Just to let everyone know that PicBasic Pro is not compatible completely with the basic used to program the Atom.
The differences are the negitive numbers. If you really need the negative numbers the you will need the newest verson of PicBasic Pro with PBPL included and then use the PBPL to compile your code. As I under stand it the SByte, Sbit, Sword variable are signed variables, PBP does not reconize signed variable, All variable will be treated as positive numbers unlike the PBPL will preserve the negative numbers. The compiler cost around 250 dollars for those who intrested.
