[ale] hex

[Stephen J. Pellicer]

You'll probably want to dig up a decompiler or debugger or something if you
want to get into directly editing machine code. While you can go directly
into decoding the hex directly for your architecture, it's not really that
necessary. You can search around on Intel's site if you're on an Intel'ish
chip for their instruction set. I found one a while back in PDF form called:
Intel Architecture
Software Developer's
Manual
Volume 2:
Instruction Set Reference

that will give you the blow by blow hex to opcode mappings. Honestly though,
with the wealth of tools out there, there's no real reason to go below the
assembly language mnemonics when looking directly at a program. Someone who
does low level programming day-to-day may have more to say than me though.
I'd look around for a good debugger or decompiler for your particular
platform though, and skip the bloody knuckles decoding machine language
directly stuff.

hey guys listen im new to hex editing and basically
all i know about it is the translations of hex to
decimal to binary... i need some documentation so I
can start programming in hex or also understand what a
program is doing in hex when i do things like... edit
notepad or something else in a hex editor. if you guys
could point me to what i seek i would greatly
appreciate it i understand this may be a bit off topic
but i figure since you guys are into linux you would
surely know a thing or two about this :) later and thanks
