Getting and Setting Memory Values
The HiWord and LoWord functions allow you to extract a word from a long word. The StuffHex procedure provides a quick way to convert hexadecimal values stored in a string into byte values in memory.
To copy a range of bytes from one memory location to another, you should ordinarily use the Memory Manager's BlockMove procedure, which is described in Inside Macintosh: Memory.
