Why does this:

Code:

format binary
  jmp   [ASD]
  ASD   dd 0

assemble into FF 2E 04 00 00 00 00 00
atleast Ollydbg and hexplorer show FF 2E = jmp [esi] Confused

or is this expected behaviour?

You forgot that fasm's default is "use16", not "use32". Wink

You can just skip the format binary and have 'use32' because fasm defaults to binary/use16.
