The following code shows the format for a Grid layout that has 50 by 30 data points:

! Grid has 50 by 30 points

! Holes have a value of 100.0

! Grid increases in X steps of 1.0 and Y steps of 2.0

! Origin of grid is at X = -20, Y = 50

GRID 50 30

100.0 1.0 2.0 -20.0 50.0

! 1500 data values follow, one for each grid point

49.875000 43.765625 38.500000 33.984375 30.12400

26.828125 24.000000 21.235610 48.877940 17.39770
