Re: Setting desired bit in a 32 bit number guess you can use this macro. #define SETBIT(bitnumber,number) (number)|(1<<(bitnumber-1))

Re: Setting desired bit in a 32 bit number guess you can use these macros. #define SETBIT(bitnumber,number) (number)|(1<<(bitnumber-1)) #define RESETBIT(bitnumber,number) (number)&(~(1<<(bitnumber-1))) Hopefully this helps.
