 106  ** this hack, and the master devil (Bully Boy) will send me to write
 107  ** Windowz software.
 108  ** BTW, for writing this hack I got personal congratulations from Dennis
 109  ** Ritchie and Bjarne Stroustrup sent me a bunch of flowers and asked me
 110  ** to participate in the standardization committee for C-- v.6.0 as
