      ColorToN( <cAttr> ) -> <nAttr>
   $ARGUMENTS$
      <cAttr>    Designates the alphanumeric color attribute that is
                 converted in NN/NN or CC/CC form.

   $RETURNS$
      ColorToN() returns a number that corresponds to the combined numeric
      color attribute.

   $DESCRIPTION$
      COLOR TO (N)umeric
      The function changes an alphanumeric color attribute from NN/NN or
      CC/CC into a combined numeric attribute.  These combined attribute
      values are useful with the CA-Cl*pper Tools functions StrScreen(),
      ScreenMix(), ScreenAttr(), and the CA-Cl*pper commands
      SAVE/RESTORE SCREEN.

      NToColor( <nAttr>, [<lColorCode>] ) -> <cAttr>
   $ARGUMENTS$
      <nAttr>    Designates the value for the combined numeric color
                 attributes.

      <lColorCode>  If designated as .F. or if the parameter is omitted,
                    NToColor() returns a string with a numeric color code.
                    When designated as .T., NToColor() returns a string with
                    the CA-Cl*pper alpha color coding.

   $RETURNS$
      NToColor() returns the designated color attribute in the NN/NN
      or CC/CC form.

   $DESCRIPTION$
      NToColor() converts a color attribute returned from another function
      in numeric form, into the alphanumeric data format.  Use this
      attribute in conjunction with the CA-Cl*pper SET COLOR TO command.
