I am currently a "bilingual" computer user (MAC and DOS).  I maintain my
calendar/datebook/address book on a DOS machine using PACKRAT.  I would
like to find a package on the MAC that gives me the capability of PACKRAT
on DOS, specifically including the following:

- ease of import/export via delimited files and other common formats 
- appointment book
- address/phone book
- to do list, with capability for inserting items due at a later date
- telephone log, with tickler for calls pending and to be returned


From my preliminary examination, it seems that no SINGLE program on the
Mac has all of these features.  I would appreciate any pointers to such a
SINGLE program, or perhaps to a suite of programs with sufficiently
seamless integration.
