OK, I see. :)

I'm aware of that. :)

with the ||, extra spaces between the strings doesn't influence the script

string || ' ' || restofstring

  is the same as

string||' '||restofstring

but without the || the above two concatenations are different

(but you already know that)

I got never stuck on that. :)  But I see your point.
