ERRBELL - (C) Copyright Glenn B. Lawler, 1990. All Rights Reserved.
ERRBELL reads from DOS Standard Input, and echos all characters to
DOS Standard Output, checks for a BEL character (ASCII 7), and sets
ERRORLEVEL to 1 if one or more are found.
ERRORLEVEL is 0 if none are found.
This program was designed to accept the output of another through
a pipe, and set the errorlevel for programs which send a BEL to the StdOut with an error message, but do not set the ERRORLEVEL.
