This program outputs a LifeLines database in modified GEDCOM format.
Two additions to GEDCOM are made: an inter-record delimiter and a
level indenter.  These are set up as global parameters and initialized
at the beginning of the main() procedure.

formatted_gedcom - a LifeLines formatted GEDCOM listing program
         by Jim Eggert (eggertj@atc.ll.mit.edu)
         Version 1,  7 September 1993


The header() procedure writes a GEDCOM header.  You will definitely
want to edit this part of the program to reflect your name and
address.  Note that I have included a line specifying Macintosh
character encoding, appropriate for my database.  You may want to
delete or comment out this line.
