using loop parameters info for renaming

hi everyone,

not sure if the logic of what i'm doing is right, so here is the problem:

- i generated sequences of nominal values which i want to compare with a test sequence
- i want to use a loop to run different distance measures
- then collate the whole thing in a single table for exporting

the first script does it with separate streams/processes and then i join them (i'll have to post this separate because of the char limit)

the second one tries to do the same using a loop parameter block, but i don't seem to be able to make it work (see below)
