The latest version of my "deflate" program works on any OS
that supports execution of coff or elf binaries or has Perl
installed in the user's PATH.  The distribution for UNIX or
Linux consists of the filePro file "deflate" containing:

  ./deflate/README
  ./deflate/data
  ./deflate/deflate
  ./deflate/help
  ./deflate/key
  ./deflate/map
  ./deflate/map.tmp
  ./deflate/new.size
  ./deflate/out.deflate
  ./deflate/prc.deflate
  ./deflate/prc.deflatev
  ./deflate/prc.trunc
  ./deflate/screen.0
  ./deflate/trunc/truncate.coff
  ./deflate/trunc/truncate.elf
  ./deflate/trunc/truncate.pl
  ./deflate/trunc/truncate.txt

When first executed it selects one of the "truncate.*" files
that works on that system, and uses it there-after.

The program creates an Alien filePro file that overlays the
target key file and first moves all records containing data
to the front of the file, and then truncates it, if desired
(allowing one unused record at its end).
