"*.doc" may be treated as a regular expression by the shell
and expanded to matching names. MS-DOS command.com doesn't 
do wildcard expansion, but other shells do. 

argv[1] being the path sounds like an some sort of MS-ism. But 
assuming that a particular compiler did that, argv[4] makes 
argc = 5.

Not if you want to re-evaluate the arguement list again without
doing pointer subtraction or making a copy of pointer to the array 
of strings :-)
