Hi all,
...think, I have to apologize
I screwed it upit is a language (spoke one...not "programming" )
thing:
I read "List of strings" which in german is "Liste von Zeichenketten".
THIS expression means this:
"A" "B" "C"
(for example).
This applied to string-join in a germenglish head for
Hi Meino,

string-join doesn't really require an 'apply'. As we can see:

(begin

Hi,
...still improving my shortwave-broadcaster-dumper... :)
