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

11 CALL FRSTPT (PX,PY)
12
14 #include <ncarg/ncargC.h>
15
16 void c_frstpt (float px, float py)
17
19 PX (an input expression of type REAL) defines the X user
20 coordinate.
21
22 PY (an input expression of type REAL) defines the Y user
23 coordinate.
24
26 The C-binding argument descriptions are the same as the FORTRAN
27 argument descriptions.
28
30 Polyline type, line width, and color can be set by calling the GKS
31 routines GSLN, GSLWSC, GSCR, and GSPLCI before calling FRSTPT.
32
33 Note that, for the sake of efficiency, the routines FRSTPT and VECTOR
34 buffer the polylines resulting from pen moves. One must be sure to
35 flush the SPPS polyline buffer before changing polyline attributes. A
36 "CALL PLOTIF (0.,0.,2)" will flush the buffer.
37
39 Use the ncargex command to see the following relevant examples: tgflas.
40
42 To use FRSTPT or c_frstpt, load the NCAR Graphics libraries ncarg,
43 ncarg_gks, and ncarg_c, preferably in that order.
