in thread missing character when reading input file

The array @ARGV was used to preserve as much of the original OP as possible. The 'BEGIN' is unnecessary, but I feel that it serves to separate the file simulation from the relevant code. No excuse for the 'do' block. It is a leftover from an earlier attempt at the file simulation.
