  If a program is called with command line arguments (or without) you'll
get two parameters passed to your main()

int main(int argc, char *argv[])

The argc argument keep the number of command line arguments (at least 1,
even if no argument is specified),
argv[0] is a pointer to a string wich is holding the path of the exe file
itself (i.e. "c:\resolve.exe").
In your example argc would be 2 and argvc[1] would point to "test.txt".
Additional arguments increase argc and the n'th argument can be read by
argv[ n - 1 ].

Good luck
Uwe
