DESCRIPTION

       X           (Real,  Input)  -  An X coordinate (specified in world coordinates) of a point
                   that specifies a position for the symbol type in SYMTYP.

       Y           (Real, Input) - A Y coordinate (specified in world  coordinates)  of  a  point
                   that specifies a position for the symbol type in SYMTYP.

       SYMTYP      (Character, Input) - A character variable that indicates the desired symbol.

                   Legal values for SYMTYP are:

                           'HI' for high pressure symbols.

                           'LOW' for low pressure symbols.

                           'ARROW' for arrows.

                           'DOT' for dots.

                           'CLOUD' for a cloud daily weather icon.

                           'ICE' for an ice daily weather icon.

                           'IS' for the intermittent shower daily weather icon.

                           'IT' for the sunny, chance of T-storms daily weather icon.

                           'MC' for the mostly cloudy daily weather icon.

                           'RAIN' for the daily weather icon indicating rain.

                           'RS' for the daily weather icon indicating rain and snow.

                           'SNOWFLAKES' for the daily weather icon indicating snow.

                           'SUN' for the sunny daily weather icon.

                           'THUNDERSTROM' for the daily weather icon indicating thunderstorms.

                           'WIND' for the windy daily weather icon.

USAGE

       Set  the  values  for the appropriate internal parameters before calling WMLABS to produce
       the desired symbol.  The internal parameters that control the appearance  of  the  symbols
       and icons are: SHT, HIB, HIF, HIS, HIC (for the high symbols); SHT, LOF, LOB, LOS (for the
       low symbols); ARS, AWC, ARD, ASC, AOC (for arrows); DBC, DTC, DTS (for  dots);  CC1,  CC2,
       CC3  (for  the  cloud icon); LC1, LC2, LC3 (for lightening bolts); SC1, SC2, SC3, SC4 (for
       the sun icon); COL.
