Default How to extract data from REALLY old Universe hashed file? - 03-01-2006 , 12:57 AM






Subject says it. Off a nearly moribund Unixware server that was
probably running UV 8.x at some point (but which isn't any longer), I'm
tasked with taking a single Universe hashed (NOT type 1) file we found
there, and extracting usable data from it.

I already tried loading it into a UV 10.x personal edition (under
Windows) system and setting up a VOC pointer, but no luck - UV says the
modulo is some huge number and refuses to work with it. My guess is the
file format has changed since 8.x and/or I've got endian problems. So.

(a) Is there any way to make Universe deal with this file? Or even any
way (looking at the file in a hex editor) that I can tell what
version/format of UV file I've really got?

(b) If not (a), are there any UV or third-party utilities floating
around to let me extract the data in any sort of usable format?

(c) If not (a) and (b), are there programming techniques in UV basic
that will let me handle the file as a single large binary blob and
break it up into records myself? (There's not a lot of data here -
under a meg - but I can see it has xFF and x00 characters in it, so I
can't just use a bunch of FIELD statements to rip it apart).

This is a personal project, not a business one, so I can't hire someone
to do it for me.

TIA for any help, advice, or school-of-hard-knocks wisdom.

If the file has a modulo over 1000 (I think), the personal version of
UV will not open it.

Although there have been file format changes over the years, UV will
generally work with old files with no problems.

Not so fast..... There is a limit to file the modulo of UV PE, about
1001, IIRC... so I'd suggest you go looking for a "normal" UV
site.....
