RE: External procs with F-specs (WAS DoW (WAS DoU...))

The USROPN is on the file spec at the top of the service program (I code all
procedures in a service program in one source member).  Then I do use %open
in each procedure for determining if I need to open the file.  I don't know
the cost of %open but most cases I don't worry about it.  The tradeoff is
that you can let all the files be opened when the service program is
activated, this impact to response time may or may not be noticeable
depending on the number of files.  If I have a procedure that is going to be
called with a very high frequency then I usually don't do it this way and
just leave the USROPN off of the file spec. for any files needed there.
