Hi Mike

Welcome to SeeSat-L.

I once wrote a little utility called "EXTRACT" which is avaliable from my web
page, including the Pascal source.  It was written to selectively extract
elements from a large (fresh) input file and write all the hits to a named
output file.  The names and/or norad numbers of the satellites you want to
extract are contained in a third file and a special case called "all.sat"
looks for the 3-line signature of a satellite element set thereby stripping
any text from the input file, yielding a "clean" output file.
