Hi all,

This weekend I decided to do some assembly hacking on some object-only code
that I've lost the C source for.  Since I haven't coded assembler for at
least 8 years, and I threw my x86 assembly manuals out when I moved 6 months
ago, there are a few things that are stumping me.

In particular, am I interpreting these instructions correctly?

0x80839fb <uttstrbyt+43>:       movzbl (%edx,%eax,1),%eax


Takes %eax + %edx, obtains the byte value in memory at that address,
zero-extends and places into %eax

0x80839ff <uttstrbyt+47>:       movzwl 0xe90(%ebx,%eax,2),%edx

Takes %eax + %ebx + 0xe90, obtains the word value in memory at that address,
zero-extends and places in %edx.
