VVSETR - Sets the value of a Vectors parameter of type REAL.

       To  use VVSETR or c_vvsetr, 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_vvsetr(char *cnm, float rvl)

       CNM         (CHARACTER,  input) is the name of a parameter to be given a real value. Only the first three
                   characters of CNM are examined. The three characters may either be entirely upper or entirely
                   lower case; mixed case is not recognized.  It is recommended that the rest of  the  character
                   string  be  used  to  improve the readability of the code. For example, instead of ´VFR´, use
                   ´VFR - Minimum Vector Fractional Length´.

       RVL         (REAL, input) is an expression, the value of which is to be given to the parameter  specified
                   by CNM.

       Use the ncargex command to see the following relevant examples: bnchmk, fcover, ffex00,  ffex02,  ffex05,
       stex02, stex03, vvex01, vvex02.
