Tony,

I think that even though 'you' are only reading them, the system is trying
to maintain their 'indices'. This is just a guess.

Hi Tim!

There are two logicals built over the RVP1 file, and they are opened at the
same time.  I have blocking turned off on the two logicals because I am only
doing CHAINs and READEs from them.  But the RVP1 file is used for output
only.
