Are you also thinking of whether the program itself counts as an
argument?

For example if, on the command line, I type:

prog1.exe a b c

Does Argument_Count() return 3 or 4? I haven't looked at this
paragraph in detail, or what surrounds it, but "the number of
arguments passed to the program invoking the function" sounds a bit
vague. Is the "program invoking the function" the shell, or the
program you're running?
