Demo ASP: syntax_error.asp 2015-04-19

We are creating a perl syntax error... this should demonstrate how error handling is done. Please check the error log file if you are interested in the output there.

You can turn this error messaging off by setting the Debug variable in the ASP config to 1 or 0.

Also here is an example of how you can use debugging, an API extension $Response->Debug(@args), in your script. The debug output will show up below, and in your error logs. This user style debugging is turned off with the same Debug setting set to 0.

Try this script also with buffering on.

This script by default does a runtime syntax error. If you would like to see a script compile error, click here.

An error has occured with the Apache::ASP script just run. If you are the developer working on this script, and cannot work through this problem, please try researching it at the Apache::ASP web site, specifically the FAQ section. Failing that, check out your support options, and if necessary include this debug output with any query.
