MAPSTR - Sets the values of certain EZMAP parameters of type REAL.

       To use MAPSTR, MPSETR, or c_mapstr load the  NCAR  Graphics  libraries  ncarg,  ncarg_gks,  and  ncarg_c,
       preferably in that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

       void c_mapstr (char *pnam, float rval)

       PNAM        (an  input expression, of type CHARACTER*2) specifies the name of an internal parameter whose
                   value is to be set. Only the first two characters of this string are examined.

       RVAL        (an input expression of type REAL) contains the value to be given to the parameter  specified
                   by PNAM.

       Use the ncargex command to see the following relevant examples: cezmap1, cezmap2, cezmap3, cmpclr, cmpdd,
