Hi All,

	I have seen in a couple of programs that use flags to set options
that work by giving a "binary" value, if you will, to each setting. For
example, the first setting has the value 1, the second 2, then 4,
8,16,32,64,etc. Then it will add up the values of the settings that have
been turned on. So if the 3rd, 5th, and 7th settings were turned on the
value would be 84 (4+16+64). The totaled value generated would be unique,
i.e. no two combinations of settings would produce the same totaled value.

	Here is the part that I get stumped on...how would one program a
function that would take a totaled value and "break it up" into the
individual values that made it up? For example, if given the value 84, it
would "break it up" as 4, 16, and 64.

Any ideas would be appreciated.

Thanks,
Joe Rojas
