Which Basic or Pascal development system for the Mac or Lisa is best
suited to enable work with indexed (sequential) files, by supporting a
(source or binary) library with at least the following functions:

 - search for a given key, returning whether found;
 - search for the key immediately following a given one;
 - looping over the data in the file in ascending or descending order
   of the keys;
 - adding or changing the associated data of a given key;
 - adding a key, with or without allowing multiple occurences;
 - removing a given key and its associated data;
 - possibility of opening several files simultaneously, with different
   key length's.

Please specify how we can get such a system if it is public domain;
or name and address of manufacturer or (nearby?) supplier, price,
capabilities, required configuration.
