[Sussex] Error codes

[Brendan Whelan]

Thanks to Steve and Jon for their responses. I hadn't realised that 
there was not a standard set of error codes which explains why I 
couldn't find the specific code.. For the record, I had looked around 
the Internet to try to find a solution. The program I am trying to run 
is a third party package (jdo) that we have been running for about eight 
years on our own server but we are now trying to run a shared system.  
Hence, I can't look at log files, run the program at a command line, 
etc. Also, the letters "jdo" are used for other things which makes 
searching more difficult.  I will look further to see if I can find 
anything on this specific program.  Brendan
