CPCGSTN searches for stations located inside specified areas
from a Vector Graphics File.

INPUT PARAMETERS
 
    VGFILE    Vgfile | scale file | attribute file | filter
    DATTIM    Date/time
    STNFIL    Station information file
    OUTPUT    Output device/filename
 
 

PROGRAM DESCRIPTION
 
    CPCGSTN lists all stations in a given station table, and
    indicates which stations are located inside areas drawn
    in the Vector Graphics File. The areas must be drawn using
    the "tick mark" special line. The file may contain multiple
    areas that do not overlap.

    If the given polygon is not closed, then the appropriate
    portion of the U.S. border is used to construct a closed
    polygon.

    The DATTIM is only used to fill in the format of the output
    listing. In this way the output listing may be used as
    input to SFEDIT.

    The output includes the station number, GEMPAK time, the flag
    indicating if the station is inside (1) or outside (0) of the
    polygon and the polygon color.


EXAMPLES
 
    1.  Identify the stations located in the polygons in the VG file
        vgf.vgf. Use the current system time and the station table
	stns_ll90.tbl. The output is displayed to the terminal.

	VGFILE   = vgf.vgf
 	DATTIM   = last
 	STNFIL   = stns_ll90.tbl
 	OUTPUT   = t

    2.  As in example 1, except the output is written to the file
        data.dat.

        VGFILE   = vgf.vgf
        DATTIM   = last
        STNFIL   = stns_ll90.tbl
        OUTPUT   = f/data.dat
