The included version has been extended with page loading via Clipboard.
It is used to deliver info about programs in the launcher etc.
Due to the excellent structure of the program, the changes were easy to make.
Changes are marked in red.
The main loop (marked in green) has been simplified by the addition of the function 'Buttonpressed'
I hope that Dav will adopt the changes

'Coded by Dav, December/2015

'A simple web browser made in smart Basic.
'Uses javascript for browsing functions.
'Has a basic bookmark manager. Only loads
'one page at a time, but I'm working on a
'multitab version right now...
'
'NEW: Shows info bar at top: Connection
' status, Time, Battery level. The
' current url now shown below menu.
' You can select it to copy url.
' Bookmark menu now drops down and
' closes up out of sight (moving).

'Dutchman added conditional recall to launcher
' and URL-transfer from launcher
