How do I read a hex value out of a file? The number was written as AAA1(not by me), but when I look at it in a hex editor the values are backwards 00A1 AA00. First off how do I actually get the value out? And secondly why is it backwards? "I can't work like this! Where are my fuzzy dice?"

The number appears backwards because Intel use little-endian byte ordering. That means that the least significant byte comes first, then the next most significant byte, and so forth right up to the most significant byte.

To read it out, just do a binary read of two bytes into a short integer.
