Hi!

If I like the commandline to be transferred like argc/argv, what do I
have to do?

How do I know, if it's a new command or just a gap in a filename?

Thanks for any advice...

Command line parameters should be separated by spaces.
If you are passing a filename that includes spaces, it should be enclosed in
quotes:

eg:   progname parm1 parm2 "c:\a filename with spaces" parm4
