1/ I really don't think you can call C-ISAM a database. (But I suppose
if MS can get away with calling Access a database ...).

2/ I have a C-ISAM 3.10 manual (in hard slip case - they don't make
manuals like that anymore) and a (p'back) C-ISAM Programmer's Manual
version 5.0 less than a meter from me.

3/ I've probably got somewhere a backup tape with code and binaries for
'cisamdtisqlperl' that I used to ship with the legal accounting system I
was responsible for 10+years ago.  Whether I can find said tape and then 
whether I have a drive to read it ...
