Hey scottn,

Thanks for sending me that. Im definitely going to take a look at it.

I dont think I explained my goals. Im still new to all this so I may have stated it wrong. Basically, I want to take a file name (with the path) as an input, and I would like the output to be a computed checksum. I believe the checksum should be a 32 bit sum of all the words I have in the bin file.

I'm going to see what that site gives me scottn but if anyone else has any solutions I'd be more than welcome to hear them. Thanks.
