NAME

       DPFRST - Specifies the first point in a sequence of points, in the user coordinate system, defining a
       curve to be drawn.

SYNOPSIS

       CALL DPFRST (XCPU,YCPU)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_dpfrst (float xcpu, float ycpu);

DESCRIPTION

       XCPU        (an  input  expression  of  type  REAL)  specifies  the  X coordinate of a point, in the user
                   coordinate system.

       YCPU        (an input expression of type REAL) specifies the  Y  coordinate  of  a  point,  in  the  user
                   coordinate system.

C-BINDING DESCRIPTION

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

USAGE

       Call  DPFRST to do a "pen-up" move to the first of a sequence of points defining a curve.  Call DPVECT to
       do "pen-down" moves to each of the other points in the sequence and then call DPLAST  to  finish  drawing
       the curve and flush the buffers.

       DPFRST  maps  the  input coordinates to the fractional coordinate system and then does a "pen-up" call to
       either DPDRAW (if smoothing is turned  off)  or  to  DPSMTH  (if  smoothing  is  turned  on)  with  those
       coordinates.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tdshpk.

ACCESS

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