Hello Jonathan,

I regularly extract subsets of my main (master) elset file.  I use a piece of 
SW called applysel.exe.  It is available at Bjorn Gimle's site at:
http://www.algonet.se/~b_gimle/programs/ibmpc/index.htm  
You may need Visual Basic in the PATH to execute it.

A typical line in a batch file would be:

applysel master.tle flasher.sel flasher.tle

where 
Master.tle is your basic large TLE file
Flasher.sel is an ascii file with your desired NORAD catalogue numbers   - 
one number to a line:
------
eg.
25400
25407
25861
----
and flasher.tle is your output file containing the TLEs from the flasher.sel 
file.
