Is perl only available for Unix ? I have used a similar technique to create an elset file when I travel to = a place far south from me. I run predictions for the vacation resort, then for (a longer time) at = my home location. My program 'buildsel filename selectionfile' can build a table of all = unique ID's found in each of the two runs. A 'dif' program finds all objects visible at the southern location = 'never' visible from home. 'applysel alldat.tle smallselectionfile small.tle' builds a clean = tle file with only 'new' objects.
