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?
