If desired, TIDY can be converted to translate everything outside of strings
to lower case (instead of to upper case) by the following procedure:

1.  Use a case translation utility (such as dd in Unix)  to convert the entire
TIDY source file to lower case. This transforms all character constants to
lower case.

  (example:  dd  if=tidy.for of=tidy.new conv=lcase)

2.  Using a text editor, delete the source code for function
KUPPER from the lower case file prepared above, and replace it
with the file KUPPER.UNX .  The file KUPPER.UNX has been altered
to convert upper case to lower case.

3.  Compile the program.
