4.4. Error Reporting
If your Perl code fails with a compile or runtime error, Interchange writes the error message from the Perl interpreter into the catalog's error log. This is usually 'catalog_root/error.log'. Error messages do not appear on your web page as the return value of the Perl tag or routine.
You will not have direct access to the 'strict' and 'warnings' pragmas where Interchange runs your perl code under Safe (for example, within a [perl] or [mvasp] tag).
