The original poster didn't say he wanted a portable way and he did say he
didn't have access to main().  The command line information is in the 
PSP.  DOS 3.+ has the entire command line, while DOS 2.+ does not have
the name of the program being executed. If you can't access with C (and
I believe that you can), you certainly can do it in assembly.
