Level 2 Help for ARC2GRAF

INP

            UNGENERATE file name.


OUT

            Output filename(s). Maximum 20.

            First  output file name is for the first  line;
            second output file name is for the second line, etc.


FLIP

            Indicates that coordinates from the input graphics 
            file/s are in Y,X ( line, sample ) format.   These 
            will be flipped to an X,Y coordinate system.

            Default is X,Y.


NLINES

            Number of lines  represented  in  the input 
            graphics file. This variable is only needed
            if the FLIP keyword is invoked.


GROUP

             An array containing the lines from which to extract
             data. Up to 20 lines may be input. However, the num-
             ber  of output graphics files must equal the number 
             of levels or the program will abort.


ALL

             Ignore groups specified in "GROUP " and produce
             one  output graphics file containing all design 
	     file graphics information.


SCALE

             Data will be divided by this scalar if required.

             Default = 1.0


XOFFSET

            X offset - value added to UNGENERATE X values.

            Default = 0


YOFFSET

            Y offset - value added to UNGENERATE Y values.

            Default = 0


FIELDS

            Input data format. Informs the program of the Fortran
            formats of the input data.


            First word contains the integer format for the line 
            descriptor. For example if the line is input in I10
            format,  the user would  code the number 10 in this 
            field. The second and third words describe the X, Y
            coordinate data pairs.   It  is  assumed that these 
            values are in F format.  The second  word  contains 
            the  digits  to the left of the decimal point;  the
            third  word  contains  digits  to  the right of the 
            decimal point.

            Defaults = 10, 15, 6


POINT

            Indicates that the output file should be in POINT
            file format.


DEB

                               Debug flag 

            Produces listing on monitor of digitized 
            types (e.g. LINE SEGMENT, LINE STRING, POINT LINE ).
            This is a program aid for debugging code.
