fileset-local: Restricting Dir Parse to 1 File of Many???

Happy March!

I know I always come here with off-the-wall puzzles.  (You should really see the things I work out on my own or the ones that keep me awake at night. 😉 )  Anyway, here’s one that I’ve been thinking about for a couple of days and I do have an immediate (an future) use for it.

I have a huge backlog to load, in this case all of the translations and any filtering have already been done and all that remains is to send the resulting HL7 messages to the vendor/application via TCP/IP connection.  The backlog has been broken down in to hundreds of messages per file, one file representing a day in the year.

The problem I have run into is that fileset-local wants to grab all of the files during a Directory Parse and I would prefer that it grab one single file, process it, send all of that data to the vendor, and then once that is complete, pick up the next file and begin the whole thing over.  I’m not sure how to make this limitation.  I do not want to do it using Advanced Scheduling because that relies on time, which would be guesswork at it’s best.

Has anyone done this?  Do you have a tcl script or somesuch you can share?

Thanks in advance for any advice or thoughts or suggestions!
