You're quite right. I read *some* instructions somewhere, but those
weren't them. Thanks!

I've read that (very helpful, thanks) and a lot of the Inside Mac book
on Interapplication Communication, and from that and your answer below,
it looks as though I may just have been lucky that it ever worked at all.

I still wonder how MPW manages it. I'm guessing (even after reading
the source!) that MacPerl is started up with an 'odoc' event in its
queue, and it sees this and puts the filename into @ARGV. If that's
right, then it might be that AppleScript is sending an odoc, but that
it sometimes gets there after MacPerl has looked for it and found it
isn't there. It's hard to tell, though, especially as I only have the
current source, not that for 5.1.3r2.

Peter.
