Hello,

I have written a small order-entry/etc. package under MS-DOS/Borland C
2.0. All works well... However, the current file searching rate is
abhorant. I have little to no experience with efficient record indexing
algorithms on an external file system, but nevertheless have installed
a rather primitive indexing method of my own, simply searching a
sequential file of keys and file offsets. Not pretty. What I need is an
indexing package for MS-DOS which will give me fast access on keys, and
one which can use my existing data structures, i.e. take a pointer to a
struct for data. If anybody has any suggestions, I would be very much
obliged. I would like to obtain a rather inexpensive Borland-compatible
C library if possible, since this package will be installed at most at
one site.

Thanks a lot.
