Hmm ok, thank you, I shall have a look at that.
I'm afraid i made an oversimplification in stating my problem: the
variable names are not actually var1_ var2_ var3_ ... but words:
something_ somethingelse_
So my question still stands: how do I get the name of a variable and
put it in a local string for each iteration
