-- November 13, 1979  10:16 AM By Forrest Changed to InitializeFTP once (and never Finalize), to use a bigger chunk in transfering (should use two buffers);  increased size of directory string to 60 from 50; Add twiddle cursor hack since people were worried about ftp dying; export Server*loaded and UserMailLoaded to eliminate 3 modules from FTP 
-- January 12, 1980  4:46 PM By Forrest Changed to used new Othello FTP and support calls to writing Raw Data
