RE: 19990315: Quick question

Hi Steve,

I just spoke with Steve Worley of SCD regarding your question and he
said he would follow up on it with you, so I'm sending him a copy of
this reply as a way to get started.

Now, the only question is whether there is anyone else named Steve that
we need to bring in on this.
