Base Address's, etc...

	Howdy,

	I am a bit confused on this subject. Lets say a base address for 
some odd device is 0x240. Ok.. that is cool, but then suddenly you need to 
write to a control register at base address +3.
 So... lets say 

static short io = 0x240;

and then I need to write to the control register, which is at 
base address + 3;

	and in some code, they define some macro, like

#define FOO_BAR (io+3)

so... when they say +3, does it mean that 0x240 becomes 0x243?

Thanks for the help
