ParseTDF is a Macintosh application I wrote originally to transfer my Sharp Wizard files to the Newton more intelligently than the dum built-in application.   It makes a moderately intelligent attempt to figure out names and companies and phone numbers and creates a slurpee file that usually does a pretty good job.

To use ParseTDF you need to start with a text file in which each contact entry is separated by a carriage return.  Each contact entry is broken down into "lines" either by tabs or by newline characters.  The first line must be the name of a person or a company.  

ParseTDF first looks at an entry to try to figure out whether the first lineis a person or an entity.  If it can't tell, it asks.  If you say its an entity, you will be asked to pick a word that the program can use to know entities in the future.  If there is one, pick it, otherwise don't.   (Don't use "and" unless you never enter a couple as "John and Jane Doe").
If you tell it "person" it tells you what it thinks is the given name and asks if it should remember it.  It the program is right, you should generally let it remember the given name.

For each succeeding line, it tries to determine whether the line is a phone number or not.

The resulting file is a Slurpee file.

ParseTDF is c. S. Millman 1995, (StephenM35@aol.com).  It is freeware.   And very limited documentation.ware.  Good luck.
