ARGI command arguments
ARGI equals the index value of the next command line argument to be
processed from ARGV. This value may be changed and will change the
array element of ARGV processed next. When the last element of ARGV is
the current input file, ARGI is set to one of two integer values:
1. the integer value of the index of the last element of ARGV plus one,
or
2. if the last element of ARGV has a string index, ARGI is set to zero.
Setting ARGI to zero, ARGC or a value for which there is no element of
ARGV with a corresponding index value, will cause the current input
file to be the last command line argument processed.
