    It says NE executables don't have a PSP.

    Is there another way of retrieving:

    1. The command line (I believe this would have predated
    the use of CMDLINE).

    2. The environment pointer.

    Thanks. Paul.

    OS/2 v1.0's SDK might shed some light. Assuming that it's available
    somewhere.

    What relevance is OS/2 v1.0 to MSDOS?

    Thanks. Paul.

    It's relevant to Multitasking MS-DOS. Not MS-DOS.

    Multitasking MS-DOS and MS-DOS are architecturely quite different, and quite incompatible with MS-DOS.

    PS) the above article describe the subject much more in-depth than
    Wikipedia.
