Charles sent me some changes that I will be incorporating and testing.
They seem to have the same design goals as my changes.

BTW:  There is a line in the patch that is messed up.  It is something


All of the ' & ' should be ' | '.  Sorry about the confusion.  It does
explain why I couldn't get the TOCHDR to re-read ;-).

Let me know if any of you have any problems with the changes.  Like I
said, Charles will be sending out a new mcd.c in the future, so these
changes are not permanent, to say the least.
