I once used a disassembler (I can't remember for what CPU) that would
put a comment on each line giving the ascii character equivalents of the
bytes.
So you would get something like (totally ficticious instruction set) :
0100 48 65 6C ST R8 (656C) ; Hel
You (the user) could then decide if the instruction or text made more
sense. Of course it didn't help with, say floating point numbers, or RAD50
strings or...
Code immediately following an unconditional JMP is
likely to be data, but
could just as easily be the destination of some other JMP, so a disassemble
can't make assumptions.
A disassembler does not convert bytes into code. It merely assists YOU in
doing that.
Yes, like all tools, you have to think when you are using it.
