Greetings, Gurus:

I have two processes on my HP3000 that access the same file.  This file
is used to "hold" transactions for a PC process to read.

The first process opens the RIO file as APPEND ONLY and performs FWRITEs
to get the records into the file.

The second process opens the RIO file as UPDATE and reads all of the
records to determine if they are for the requesting PC.  Then it
performs an FDELETE.

Well, this seems to work....a little :-).  When the first process puts a
record in the holding file and the PC queries for it, it returns one
record and performs an FDELETE.  If the PC immediately queries again, it
is told that there are no records available.  However, when the first
process appends another record to the holding file, the PC queries and
receives TWO records.  If the PC immediately requeries, it is told that
there are no records available.

I am sure there is a better way to do this, but I am not sure how.  It
appears that my FDELETE (inactive RIO records) are being trampled on
subsequent writes from the first process.

Any ideas??  I am desperate.
