Well, much ado about nothing - they got it sorted before I could get there.  
 
Thanks for the input all.

Thanks Andy and Arthur - probably later this week after I've been to have a look-see.

I wrote two books about Clipper, and am close friends with its original 
author. I can probably tell you anything you need to know. 

Your dBASE skills will port to the extent that the authors of the system 
did not exploit Clipper-specific language. By version 5 Clipper was a 
lot different than dBASE, with OOP constructs, UDFs and a lot more. 

As for fixing the indexes, that depends on the RDD that was used. 
(Replaceable Database Driver). You can discover this by looking at the 
#include files. In most cases, you could write a simple program that 
walks through the list of tables and recreates the indexes, but that 
assumes that you know which columns were indexed. 

Let me know if you need further assistance.

I have had a request to look at a Clipper system where (apparently) the 
indexes have become corrupted.  The prospective client is a distance 
away and I want to evaluate my chances of succeeding before I travel. 

I did a lot of dBaseIII / IV  stuff quite a few years ago, but nothing 
in Clipper.  Back in those days, I had the impression that dBase and 
Clipper were very similar, and with Clipper you could 'compile' the 
processing module(s). 

Can someone tell me how well my dBase skills will port to Clipper?  And 
if it's a 'compiled' system, is the source held separately?  And are the 
indexes in Clipper like the indexes in dBase which are easy to 
re-construct? 

Any middle-aged fellow travellers out there who can help?  Tips, Tricks, 
Traps? 

Cheers 

Stephen
