Re: [Dev-C++] My Operating System...

[Per W. <pw...@ia...>]

Note that if you make your completely own OS, you might use any method you
like, since you have to implement it yourself.

Alternative 2 - using msdos.sys + io.sys and just replacing the command
line. One again, you might use any method you like, since msdos will only
specially handle the first two arguments meaning that the command.com
replacement must contain full commandl line parsing.

Alternative 3 - you are still going to use command.com. Then - I haven't
an old MSDOS available so I can't test - I assume you have to run your
commands as dir.exe, md.exe etc, since command.com will otherwise process
the built-in commands dir/echo/... as reserved words and process by itself
without looking for any external program with the same name in the
program path. Anyway, if you manage to start your own external programs,
the command line parameters will be available exactly as if you write a
normal dos or win32 command line program.
