I have some application programs developed under SCO Unix.
Now I have installed SLS 1.02 and hope to run those SCO binaries
on Linux, but it didn't work.

As I know, COFF is the executable file format of SCO and gcc can
generate COFF file format. So, my questions are:

1) What is the executable file format of Linux?
2) Do I need to modify Linux kernel to make COFF file format to
   be executable on Linux? (Or any alternatives?)
3) Is there anybody have similar problems and solved it?

Any comment and advise will be greatly appreciated.
Thanks in advance.

	a.out.

	Yes, I have patches to make it possible to drop in modules so that the
linux kernel will understand different executable types.  Currently I have
modules for a.out and ELF.  COFF and others should not be that hard, and the
patches to the kernel will be very clean.

	There are other problems that need to be solved before you can run the
SCO binaries under linux, and the main one is that you need compatible
syscalls.  Again, a lot of the legwork is done here, and the only thing that is
really needed is for someone to sit down and hammer out some of the details.
Some of the simple syscalls are already done, just the more complicated ones
remain.
