I will try to comment although I don't know what you are trying to achieve ....

First - why are you using string here and below you are converting into "to-url"
once again? What about:
currentpath: ftp://blah:[blah--blah--org]/blah/blah/
rebol says:
->> type? currentpath: ftp://blah:[blah--blah--org]/blah/blah/
== url!

hmm, I don't understand here. Are you repeating above blocks five times here or you
just tried to show us your loop repeats five times? There is several issues
however:
- maybe more convenient loop could be used, e.g.
for i 1 (length? path) 1 [code-here] ; so you will achieve a little bit more
dynamic aproach ...
so in the case of using for i .... you would do 'append currentpath path/:i
- append currentpath first path ; modifies currentpath and there is no way back
....
what about just one line?:
workpath: join currentpath [first path "blah.data"] ; in the case of my advice
about using url directly it would be %blah.data and in the case o using for i ...
path/:i
that way currentpath will not be modified. 'Join will join each member of block to
'currentpath but will not modify it and 'workpath is gonna point to the result ...
- currentdata: join {"} [load to-url workpath {"}] ; just one line once again ...
also - why to use char datatype? look how I enclosed " ....

join currentBLAH? :-) a bug or ... any way - I would suggest using rebollish
current-path, current-file naming convention ...

If it will not help, send me a real code, except the names and passwords ...
