A long, in fact a *very* long, time ago I think I read a paper that investigated if visual programming was as good as many claim it to be.
If I remember correctly the conclusion of this paper was that it wasn't with the exception of concurrent programming on a 'high level', unfortunately I don't remember the title of the paper, where it was published, who the author was or anything else (I think it was a single author, male and possible the surname starts with an "S" - at least "S" pops up when I try to remember something about this paper). Does this very sketchy description remind someone of a paper/author? if so I would be very grateful if you could send me an email (because I can find anything about this). - jem -- The Open University is incorporated by Royal Charter (RC 000391), an exempt charity in England & Wales and a charity registered in Scotland (SC 038302).
