[AccessD] OT: Clipper

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.

Subject: [AccessD] OT: Clipper


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
