/*
Usage: STRIP <infile> <outfile>
This program strips the high order bit from each byte in <infile> and
creates <outfile> from the stripped data.
Modifications:
15/Jun/1982
Originally from BDS "C" UG but took forever to run due to printing
a running total of characters processed. Modified to print only a
total character count at the end. Bill Bolton, Softwate Tools,
Australia.
