-------------------------------
You will have to create your own font and select the spacing between
between them to be zero (use the "SPACING" option in EDFONT).  Or, you
could make copies of the system font you want to use and change the
spacing in there. The problem with this is that your characters might
seem to run together when displayed.  I don't believe there is
any other reasonable solution other than clearing the text box first.
