So maybe someone can refresh my memory so that this doesn't look
bad to me.  Two things seem wrong:

1.  The assignment of an invalid date value to a date type
field resulting in storage of the invalid value,  and

2.  Cancelation of the Del key (for *nix) not re-focusing
an input statement.

Maybe this is the way it's supposed to be and I just forgot.
