Hi Ian,

And thus Ian let it be known to Peter:

  PL>> A function is used to return one value.

  IS> Ain't necessarily so - a function may return var parameters just like
  IS> any other procedure, as well as its function result:

Ok.. I see.

I was just repeating how I have been taught to use functions at TAFE.. it's
the schools' approved usage of functions.  :)

Cya,

Pete
