After having disposed of window and screen management packages, I'm on
the lookout for database libraries for MSDOS. Does anyone have any
experiences?
I have been looking at some shareware offerings and some commercial.
I have not found any that supports compound keys, which I know I will
need. With compound keys I mean keys that consist of several record
fields, in some suitable order. This will make it easy to
retrieve records, correctly sorted, even on subkeys.
Example:
Imagine a database with library cards. The keys are
[1] Author, [2] Title
Now if I insert a number of 'books' into the database, and then
retrieve them on key [1], I will get a bunch of record with
one author, but with unsorted titles. I will have to sort
this collection before I can display them. This seems unneccessary.
Now, If I had the possibility to specify the key consist both
of field [1] and [2] the sorting would be done automagically by
the database.
Does anyone know if there is anything like this available?

C-Tree will do what you say you want, but C programs are not as
flexible as you might like (compared to, say, dBASE).

C-Tree will do that, no problem.
