How to cancel/stop a report ?

Hi,

I wrote some controls in all my scripts and sometimes they are at the beginning, so the report don't create the outputObject. Then, I can stop the report with a userDialogs who describe errors.

But my question is how I can stop the report at the middle of execution whereas I already create the outputObject? If I do this, the outputObject appears on the screen even if I don't execute the line "outputFile.write()"

thanks for your help
