PS: Could you please change the name of the B4X Basic Language booklet into B4X Language in the Documentation pages.

I'm uploading the correct Booklets zip. Should be online in a few minutes.

New method ?

The B4X Booklets have been updated to version 2.4.
Changed all links to show the inline booklets.
I assume the only changes are the links. The contents are remain the same as version 2.3.
