        Data type: LOGICAL
      
        Access: Readable/Writeable
      
        Applies
to:
        FRAME widget
      
      The
SIDE-LABELS attribute returns TRUE if the frame displays labels
to the left of each field rather than above each field.
      Note: For static widgets, colons are appended to the end of side
        labels by default. To create side labels without colons automatically added, the r-code must
        be compiled with the -nocolon startup parameter in effect.
        See the Startup Command and Parameter Reference for more
        information.
