Just a short note, made a dumb mistake in the first version. The API interface
did not work properly. Forgot about stack frames.

The enclosed files are:
    checkdv.asm   contains the library functions to check for Desqview
    dv.h          contains the global declarations for C programs using
                  the dv functions
    testdv.c      quick program that just tests the dv environment and
                  returns the buffer address.
