Setting the global variable $DEBUG above the class declaration will provide significant feedback above the webpage's Title Bar and a small amount of feedback in the Message Area below the Menu Bar. If $DEBUG is set at a higher order (eg. std/page.php), the small amount of feedback in the Message Area will also be generated.

As an example:

ATTRIBUTE: seq= Array ( [isa] => int
                Read/Writable? = 1
                Initialize Value =
                Attribute Object ( [key] => seq [vals] => Array [name] => [read_writable] => 1 [isa] => integer [trigger] => [doc] => [type] => string [subtype] => Array

Verb is set? 1 (count)
Attribute exists? 0 (lms_audit)

Setting the global variable $DEBUG above the class declaration will provide significant feedback below the webpage's Footer. If $DEBUG is set at this level, any pages loaded after it by the system will also have its debugging activated. $DEBUG may also be set in cgi-bin/settings.php.

As an example:

PHP used 1,108 KB at peak emalloc usage.
PHP used 1,311 KB at peak memory usage.
