ELIminate direction range
The ELIMINATE line terminates mesh points along lines in a rectangular grid.
X.direction = logical Y.direction = logical
These parameters determine whether to eliminate points along vertical or horizontal lines. One must be chosen.
range
IX.Low = integer IX.High = integer IY.Low = integer IY.High = integer
Points along every second line within the chosen range is removed. Successive eliminations of the same range remove points along every fourth, eighth line, and so on. For horizontal elimination, the vertical bounds should be decreased by one at each re-elimination of the same region, and conversely for vertical eliminations.
Points along vertical lines between 10 and 20 are removed.
