Visual programming sounds nice, but in practice it is of limited use. If you have a smallish number of modules to link together, you could do this as easily by hand-coding. If you have a larger number of modules, you probably ought to think about simplifying the system! Rob MacAulay Rob MacAulay Cambridge

not come across this problem. Incidentally, you should check out Doatse Swierstra's parsing combinators, which are *very* impressive: http://www.cs.uu.nl/groups/ST/Software/Parse/ (It took me a few days to work out how to use them, but once you have done that, they are very quick to use)
