Yes "next" did the trick.
Thank you very much indeed!
I lack the visibility to see how "next" is a replacement for "break" i.e. "last" seems a far more more natural replacement to end a loop. "last" certainly stopped any more bindtags being looked at but also took the interpreter out at the same time suggesting that the loop is the main message loop.
It never occured to me to try and continue that loop.
Once again thanks.
BTW is there a best place/file I should be looking at to get your level of understanding re Tkx?
