'System Documentation'?

This may seem like an utterly stupid question, but where can one find API documentation for X++? The e-Learning courses mention method listings in the ‘System Documentation’, but I have had absolutely no luck finding it. The Developer’s guide includes an Axapta language reference, but while this covers every aspect of syntax, precedence, etc. It does not contain a function reference. Thanks.

Aaaah, OK. By ‘System Documentation’ they meant the node by the same name in the AOT. As stated before-stupid question. [;)]
