WMLABC - plots weather map city names and daily hi/lows.

       To  use WMLABC or c_wmlabc, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.

       #include <ncarg/gks.h>

       void c_wmlabc(float x, float y, char *city, char *temps)

       X           (Real,  Input)  -  An X coordinate (specified in world coordinates) of a point that specifies
                   the center of the composite label that consists of the city name in  the  character  variable
                   CITY  and  the  temperature ranges in the character variable TEMPS.  The city name is plotted
                   above the temperatures.

       Y           (Real, Input) - A Y coordinate (specified in world coordinates) of a point that specifies the
                   center of the composite label that consists of the city name in the character  variable  CITY
                   and  the  temperature ranges in the character variable TEMPS.  The city name is plotted above
                   the temperatures.

       CITY        (Character, Input) - A character variable that contains the name of the city being plotted.

       TEMPS       (Character, Input) - A character variable that contains the daily hi/low label for  the  city
                   named in the third argument.

       CALL WMLABC (X, Y, CITY, TEMPS)

       Set  the  values  for  the  appropriate  internal parameters before calling WMLABC to produce the desired
       label.  The internal parameters that control the appearance of the labels are: CBC, CHT,  CMG,  RFC.   To
       mark the cities' position with a dot, see the documentation for WMLABS.
