moritz,

I have never used 'wantarray', but I will now. I looked all over for something like 'scalar', but for lists. I like the comment in the Camel book, '...should really have been named "wantlist"...'

I'm going to put it in the code, so I will remember how to use it, but the sub 'UnPackOne' is faster for 1 element. I still wanted to know how to return a list of one.

Thank you
