/*
Purpose:
MAIN is the main program for ARGS.
Discussion:
ARGS reports on the command line arguments.
On input, ARGC is the number of command line arguments (including the
program name itself), and ARGV is a pointer to an array of pointers,
the null-terminated strings that constitute the command line arguments.
Thus, if we have invoked a program by:
fred 1 alpha 3.7
then on input
ARGC is 4, and
ARGV --> ARGV(0) --> "fred"
ARGV(1) --> "1"
ARGV(2) --> "alpha"
ARGV(3) --> "3.7"
