Actually, isn't 4 bits, to be in keeping with the quaint spelling of byte, a nYbble?

>16 bits = word
>32 bits = double word

>>One word is 32 bits. A dword is a double word, so it's 64 bits (or 8 bytes).

>>>Also, what would you call something that is stored as base 256 (the passed in string seems to be base 256). I was thinking of calling the above function 'StringToDWord' but 'string' is a bit ambigous. Note: if worrying about a function name seems 'anal', I have a large library of functions and I think it is important to name them correctly!
