C-Isam products ?

[Glen Eustace]

I am trying to find an Indexed-Sequential file management library (
with source, if possible ), for DOS and UNIX.  My intended
application makes support for multiple keys essential.  The Unix
platforms are DEC (Ultrix-Risc) and Pyramid.

I have seen and Ad. from Byte Designs Ltd. for a product called
D-ISAM.  Has anyone used it or another that may suit.
