EXIT CODE 255

[marlboroguy58]

hi, i have a script which extracts data from a flat file, formats it and populates that data into an Excel sheet. I noticed that if the flat file is small, the script runs and exits with code 0, but if there is a lot of data the same script populates some part of the data and exits with code 255. i m not a perl expert, but think that the perl.exe is losing the CPU time and hence exiting...not sure.. i m using windows XP professional. once i run the script there will be 2 processes running perl.exe EXCEL.exe as soon i run the script i set the priority of the perl.exe process to "real time", the script runs succesfully, but with the default priority it exits with code 255. how do i prevent the script from coming out...is there a way i can set the priority of the script from within the script..

I just did a quick google, and found that you should be able to control the priority of tasks by using this command to start them:

start /belownormal program.exe

I found this at http://www.comptechdoc.org/os/windows/win2k/win2kprocess.html.

Reviewing this, I suggest a couple of minor modifications to meet the OP requirements:

start /realtime perl theprogram.pl

Moron:

Ha, ha! That's quite correct++. When I read the original post (OP), it made me start the google search because I have a similar problem. So my response answers my problem rather than the question in the OP.

Thanks for the catch, Moron.

The priority of the process shouldn't cause it to exit, unless there's some time limit in the program. To figure out why it's existing, try running it from a command shell, and see if it prints a helpful error message before exiting. If that doesn't help, try adding error messages in the various places that it exits, adding debugging messages in the code, and/or running it under the debugger.

Good luck!
