RE: [SQL] function parameters/output values

Peter,

Thanks for responding!

We looked at Chapter 4, and could not conclusively determine whether this
was the case. Can you point us to a specific page, paragraph, etc.? Can you
point us to some code examples (outside of the documentation)?

(Why isn't this in the FAQ... seems to be a very common question... and yet
almost impossible to conclusively determine by searching through the mailing
lists or documentation...)
