# ARGC The number of elements in the ARGV array.
# ARGV An array of command line arguments, excluding options and the program argument,
# numbered from zero to ARGC−1.
# The arguments in ARGV can be modified or added to; ARGC can be altered. As each input file ends,
# awk shall treat the next non-null element of ARGV, up to the current value of ARGC−1, inclusive,
# as the name of the next input file. Thus, setting an element of ARGV to null means that it shall
# not be treated as an input file. The name '−' indicates the standard input. If an argument matches
# the format of an assignment operand, this argument shall be treated as an assignment rather than
# a file argument.
