To IBM 360 architecture, a word is 32 bits, or four contiguous eight-bit bytes. In Intel's PC processor architecture, a word is 16 bits, or two contiguous eight-bit bytes. I do not miss mainframes! :)

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!
