Coordinate System Data Records

  A Coordinate System Data Set is denoted by a `KEY' of 107 in the data set header record.

KEY, LPNR, TYPE, NANT

To be read with the format:

FORMAT(1X, I2, 3I5)

Where:

KEY = -1 for a data header record

= -3 for the data set delimiter record which is an otherwise blank record inserted at the end of the data set.

LPNR = Sequence Number

TYPE = 1=Rectangular, 2=Spherical, 3=Cylindrical

NANT = Number of nodes to follow

And then the system data:

KEY, XX, YX, ZX, XY, YY, ZY
KEY, NODE1,...NODE15

To be read with the format:

FORMAT(1X, I2, 6E15.5)
FORMAT(1X, I2, 15I5) or FORMAT(1X, I2, 15I10) for 10 digit node number format

Where:

KEY = -2 for a data continuation record

NODE1 - NODE15 = node numbers

Notes:

1.

The node numbers will be repeated until NANT nodes have been output.
