Hi Alan and other Gurus,

if you look carefully at the string below, you see
that in amongst the "\x" stuff you have the text I want:
z tfile://home/alpha
which I know to be an address on my system, plus a bit of preceeding txt.

So I believe this is the right approach. in fact, If I print the string, 
without any modifications:
I get the following sort of stuff:

So this is one approach that will work.
I have no idea what sort of encoding it is, but if someone could tell me 
how to get rid of what I assume are hex digits.
In a hex editor it turns out to be readable and sensible url's with 
spaces between each digit, and a bit of crud at the end of url's, just 
as above.

Any suggestions with that additional info?
I've used struct before, it is a very nice module. Could  this be some 
sort of UTF encoding?

I think I was a bit light on info with that first post.
Thanks for your time,
