Demo ASP: syntax_error.asp	2008-12-04

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.
