Reporting Problems or Possible Bugs

If you find what seems to be a problem or a possible bug with GEMPACK, please report it as indicated below.

We are usually able to respond to such reports within 48 hours. If a bug is found, we are usually able to send a bug fix within that time.

Save Files Before Trying to Work Around the Problem

If you find a possible bug, we know that you will want to try to work around it.

But please, first save the files as they are. Otherwise we know from experience that you may find it impossible to reproduce the problem.

If we can reproduce a bug, we can usually fix it quickly. But if we cannot reproduce it, we probably cannot help.

Sending Files Needed to Reproduce the Problem

Please zip up in a single ZIP file all files needed to reproduce the problem.

Then convert the ZIP into an R42 file as described here. Attach the R42 file to your email.

If the problem occurs in a simulation (with GEMSIM or a TABLO-generated program), we need all files beginning with the TAB file. So please zip up the TAB file, the Stored-input file used to run TABLO, the Command file, all starting data files, and any shock or supplementary data files needed.

Please include in the ZIP/R42 file, the LOG file from your run which shows the problem. This is important for us to know that we have reproduced the same problem as you saw.

Please also send a brief description of the problem. This might be something like:

Please send the R42 file and information about the problem to GEMPACK Support. Please attach to your email a copy of the diagnostic file that you can generate with ViewHAR (see below).

Checking That You Have Included All Files

If possible, please unzip into an empty directory the files you think are necessary.

Then run the job(s) again to check that you have all required files and that you can reproduce the problem. [If the problem is with a simulation, make sure that you start by running TABLO.]

This is what we need to do to reproduce your problem. If the above works for you, chances are that we will be able to reproduce your problem from the R42 file you send.

The Diagnostic file

You should send us a copy of the diagnostic file, which tells us what operating system and CPU you run, how much RAM and free disk space you have, and many other facts that may be relevant to your problem.

In ViewHAR, go Help....About/Diagnostics and press the Diagnostics button. A diagnostic file should be displayed, which you can save or copy to the clipboard. Other GEMPACK Windows programs work in a similar way.

If The Error Comes When You Are Using RunDynam

Then getting the relevant files into a R42 file is easy. Just ask RunDynam etc to make a Zip Archive using menu item
Zip..Save Ingredients as ZIP archive

Then convert the ZIP to an R42 file using the WROT42 program that you can download from here

We also need the LOG file so that we know whether or not we have reproduced your error. And please tell us which year/period and which run (Base/Rerun/Policy) the crash occurred on.

Unfortunately RunDynam ZIP Archives can be very large - sometimes too large for email. If so, you may be able to send yours to us via the web site

Reporting problems with Windows programs

If you have a problem with a GEMPACK Windows program such as ViewHAR or TABmate, you should, as described above, zip up and send to us any input files needed to reproduce the problem. You may need to describe the precise sequence of button-clicks which led to the problem. Sometimes a picture is useful, which you could save in a Word document as follows:

In addition, you should send us a copy of the diagnostic file that is generated by the problem program. Go Help....About/Diagnostics and press the Diagnostics button. A diagnostic file should be displayed, which you can save or copy to the clipboard.

Which ViewHAR.EXE?

You may have several copies of a program, eg, ViewHAR.EXE, on your hard drive. For example, ViewHAR.EXE may exist in your GEMPACK (usually C:\GP), RunGTAP, or RunDynam folders. RunGTAP and RunDynam usually use their own local copies of ViewHAR. If there is a problem, you'll need to identify which copy of ViewHAR.EXE is to blame. Perhaps several copies of ViewHAR.EXE will have to be replaced.

You can use the command line to find the different ViewHAR.EXE files. Open a DOS box, and move to the C\: root by typing:

cd \

Then type:

dir/s ViewHAR.EXE

Open the ViewHAR that caused the problem, and use menu command Help....About/Diagnostics. The About screen tells you the location of that ViewHAR.EXE.

Quite often, problems with Windows programs may be resolved by downloading and installing the latest versions. You may need to install the update three times, in your GEMPACK (usually C:\GP), RunGTAP, and RunDynam folders.

We value informative bug reports
