There used to be toolkits for c that did stats, complex numbers, file handling, etc.

The Vermont library was the one I remember best. They got bought out by the Waite Group. I think. The way of the 90's. Anyway I cannot track the library down on the net.

It doesn't matter, but what I'm looking for is the ISAM library.
In fact ANY ISAM library would be cool. HPUX ISAM support would also be cool.

Any suggestions for libraries you folks have used?
