RE: Service Program Question.

["Stone, Brad V (TC)" <bvstone@xxxxxxxxxxxxxx>]

That's what I thought.  But when you said to remember to close the files in
the service program, I thought there was something else.

I played with that... ran into problems.  Especially when checking the open
status of a file.  It didn't alway return the right value.  Bif or INFDS.
So, I just don't worry about it.  

I dont know of any programs I have that just do a sequential read anyhow, so
it's no biggie.  That's what access paths are for.  ;)
