NAME

       VECTOR - generates a "pen-down" move to a specified point in the user coordinate system.
       VECTOR is used in conjunction with the routine FRSTPT to draw lines.

SYNOPSIS

       CALL VECTOR (PX,PY)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_vector (float px, float py)

DESCRIPTION

       PX          (an input expression of type REAL) defines the X user coordinate.

       PY          (an input expression of type REAL) defines the Y user coordinate.

C-BINDING DESCRIPTION

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

USAGE

       Polyline type, line width, and color can be set by calling the GKS routines GSLN, GSLWSC,
       GSCR, and GSPLCI before calling VECTOR.

       Note that, for the sake of efficiency, the routines FRSTPT and VECTOR buffer the polylines
       resulting from pen moves.  One must be sure to flush the SPPS polyline buffer before
       changing polyline attributes.  A "CALL PLOTIF (0.,0.,2)" will flush the buffer.

EXAMPLES

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

ACCESS

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