Hi.. I have a program that is written in dbase IV and compiled. The person who purchased the program does not have the source code and the company that wrote the program no longer exists. Is there a tool that will allow me to decompile the code? So I can recompile under a windows version? When I run it under Windows NT 4.0 it won't run..."file already open" error. Is there some way I can get it to run? Any help will be greatly appreciated...

Bill - There's no tool to decompile dBASE code, but there is -- or was -- a
service that promised to do so. See below. However, the error message
suggest you're running into another problem.
Versions of dBASE IV earlier than the final build (xx71) of dBASE IV - 1.5
produced this error when attempting to index or sort on computers running
faster than about 33 MgHz. Your options seem to be:
- Upgrade to build xx71 of dBIV-1.5 or any build of dBIV-2.0 or dBASE 5.0
for DOS. Unfortunately, none of these are still sold by Inprise. One or
another might be available from a software distributer or from a former user.
- Slow down your computer to 33 MgHz, or use one that runs at that speed (or
slower).
- Try a TSR/BIN called IDXFIX. This was not provided or recommended by
Borland/Inprise (or TeamB), so you use it at your own risk. Some who have
tried it say it has worked for them, others say it hasn't worked.
- Try to run your app in Visual dBASE 5.6. You will have to convert at
least your reports to make this work at all, and you will probably need to do
much more to get something even marginally satisfactory using your old code.
- Learn to work in Visual dBASE (it's a very different programming world
from dBASE/DOS), then redesign and rewrite your app from scratch for the new
environment. For this, you should probably skip VdB 5.6 and start with the
current version, Visual dBASE 7.01.
If you still want to try decompiling your dBASE/DOS code: Some years ago an
outfit in England called 4 D Concepts offered a decompile service. I don't
know how well it worked, or if they are still in business.
Their email address at that time was:
100040.366@compuserve.com
If that no longer works, their mail address was:
4 D Concepts Limited
PO Box 1221
MARLOW
Bucks SL7 1WB
United Kingdom
They posted a more detailed description of their service, which I
would be glad to email to you if you wish. However, it would seem
to make more sense to see if they're still in business, and if so
to ask them directly what their current offerings might be.
