In a while generating hex by hand becomes a great pain. :-) (especially if you do multi-platform assembly at the same time) Over a year ago I wrote a perl script which uses gdb to generate left 4 columns automagically from an assembly code. Check out easyshell_sparc tool in this tarball: http://www.notlsd.net/bof/sparc-tools.tar.gz, could come handy~ ;-) (this is sparc-specific version, but I've got templates for hpux/x86 if interested, didn't really bother making them public though).. -FY -- http://www.notlsd.net PGP fingerprint = 56DD 1511 DDDA 56D7 99C7 B288 5CE5 A713 0969 A4D1
