Thren you understand exacrtly what I asked. But how do I use it? I managed
to save it to the Scripts.Lua directory. Then managed to find where that
was and open it (not very easy - Fred how about an Iconbar menu entry
"Open scripts")

Retyped it to Lua.

Dragged it onto the scripts icon of a window containing the RiscOS URL
(shift dragged from disc).

Also tried adding       #! lua  at the beginning


Ain't nuttin done happen!


I don't understand scripts and have looked at Lua .. grappling with a
small amount of Perl is difficult enough. But another language... Life's
now too short (I'm 66!).
