Dear List I am still listening, and though I don't have to do what I originally asked about, it has been very instructive to read your responses. Thank you all! What I was going to do (but now don't have to) was to set up a print spooler. I thought (wrongly) that the second hand printer I had brought into the office could not be connected to the AppleTalk network. I still wanted to make it available to the network so I set upon the idea of connecting an old PowerBook to it and networking the PowerBook. With that in place, I was going to set up a shared folder on the PowerBook into which people could stick stuff for printing, having done a print to file and having the location of the file in the shared folder. The Perl script (running on the PowerBook) was then going to examine the contents of this folder and having found a file that was no longer 'busy-being-filled', would take same and parcel it off to the printer. That was the idea. Thankfully (but with some disappointment) I did not have to do it, as the printer was in fact networkable. Again, thanks for your input. I am still interested to know how you can know, for sure, that the file is not open and thus is available for processes similar to that which are outlined above. Sincerely, Bruce M.
