title: DOS debug like program for 32-bit x86 assembly
body: <p>Many of you may recall the old DOS program--debug.  Though outdated in many respects, one of the nice things about it was that one could easily find the byte-sequence for a given instruction without having to go through the steps of writing a program, compiling, disassembling, examining the file contents, ....  Enter the instruction, then dump the instruction address.  'debug' regrettably does not do 32 bit instructions.</p>
  
  <p>Does anyone know of a tool that does something similar for 32-bit x86 instructions?  I don't want to go through the whole compile process; I just need to be able to enter a couple of instructions and have it spew out the length of the instruction and its byte sequence.</p>
