     I've been using GNAT 3.15p for a long time to write DOS-like
project utiities to run on my Wintel desktop.  I've just come up with a
case where I'd like to implement optional parameters.  Since the utility
is DOS-like, I want to use the DOS form of optional parameters: attached
to the name of the command, separated by the '/' character.

     I don't see how to do this.  Command_Line.Argument doesn't accept a
value of 0, which I remember as being the substring of the command line
from the first non-blank up to the first suceeding blank.  The note in
A.15 says that Command_Name is the equivalent of argv (0), but in GNAT
that's really just the command name, options stripped off.

     Does anybody have any suggestions?

                        Charlie
