I'm not sure if RDOS has it, and who knows what the others (e.g. Real/32) have. I'm not up for testing everything! ;-) Anyways, I was just trying to be exhaustive, saying that you can't expect it to work 100% the same in all scenarios and OSes, but I lack the experience to say specifically. It's more complex than it sounds. -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
