The value of
argv[0] is a pointer to a null byte when the program is run on DOS versions prior
to version 3.0. For
DOS version 3.0 or later, argv[0] points to the program name.
The remaining argv strings point to each
component of the DOS command-line arguments.
Whitespace separating
arguments is removed, and each sequence of contiguous non white
space
characters is treated as a single argument. Quoted strings are
handled correctly (that
is, as one string containing spaces)
