Natural programming guide & Natural users manual

Hi, everybody.
I am an old natural-adabas mainframe developer.
Excuse me, where can I found these two pdf manuals ? I have got both on printed paper ten years ago.
Thank you for your help.

Hi Javier,

documentation is available via Empower (empower.softwareag.com) or TechCommunity.
For TechCommunity, click on Forum in the header bar and the select Documentation.
You might need to request access to these pages if this is not already set.

Regards,
Holger

Thank you very much, Holger.
I need to upgrade my knowledge.
