I certainly don't like the look of this!  I would prefer to get the command line
as a single string which I can parse myself.  This is the approach taken by
Stony Brook.  Their library has a procedure, I believe its called GetCommandline,
which returns the command line for the program as a string.  While parsing the
command line yourself may be more work, I think it is more flexible than the
approach above, unless I am missing something.
