I am not sure how you are supplying filenames. I do all the queuing in a
node/javascript backend. So when SOAP wants to know which file is next, it
does an HTTP request and I return the file name and pass along the SQL
rowid. That way, when SOAP starts playing it, I have ON-TRACK which picks
the rowid from the meta and sends it back to the node backend to update.
In looking at your question closer though, it looks like you have a
different problem. Assuming line 40 is the CMD= line, 'filename' is local
to the process_metadata function, which means it isn't defined outside that.
You need to (in the main body)
filename=ref "*"
and then in process_metadata
filename := metadata["filename"]
Hope this helps.
