To view memory at a given address, I usually use the "x" command.
To write memory, I use "set {TYPE}ADDRESS := VALUE" (or something
like that, I'm completely jetlagged right now). For instance, to
set a byte at 0xdeadbeef to 0x48, I would do:

    (gdb) set {char} 0xdeadbeef = 0x48

(This assume that the current language is C)
