Hello,
No problem. If anyone of advanced users is willing to add comments to AFL library you can do this
using this link:
http://www.amibroker.com/guide/afl/view.php?name=<THENAMEOFTHEFUNCTIONHERE>
I have just implemented notification mechanism so I am notified about every comment
sent so I can check it for correctness.
Please do not use comment feature to ask questions.
Best regards,
Tomasz Janeczko
