keep backups of the original and when every you modify it, recompile it.

That looks like a lsp file that was "protected" using PROTECT.EXE. This was a utility included on the R12 Bonus CD (http://www.cadtutor.net/forum/showpost.php?p=119360&postcount=13). There is also a tool called the Kelvinator (http://through-the-interface.typepad.com/through_the_interface/visual_lisp/index.html) that may have been used. It was included on the same CD.

Since R2000, "compiling" to FAS or VLX has been included with AutoCAD.
