thanks, FYI, VMS has a few gotchas with how it treats directories ...
I have occasionally ran into
situations where my only solution was to recursively remove all
logical roots from the directory
spec (until I had the 'real' path) and then use that (unfortunately,
that is not a guarantee of it
working in swish-e, as I found in my testing yesterday)
