UDF description

Hi

I sent this a while back, but never received it from the listserver.

The LRM 2.3.1 has this to say about UDFs.

An analog user defined function:
...
— shall have at least one input declared; the block item declaration
shall declare the type of the inputs
(whether they are input, output, inout)

This doesn't seem to be clear English to me, implying that an UDF can
have an "input" that is an "output". Unless I've misunderstood, wouldn't

— shall have at least one formal argument declared; the block item
declaration shall declare the type of the formal arguments
(whether they are input, output, inout).

be clearer? (Assuming that "formal argument" doesn't need defining).

Regards
Paul Floyd
