thx Thorsten this is great!
will use it over the next few days and report bug (if any) that i find best Z On Tue, Aug 19, 2014 at 5:14 PM, Thorsten Jolitz <tjol...@gmail.com> wrote: > > Hi List, > > I've written the "eierlegende Wollmilchsau" of wrap-in-block functions > (i.e. the 'all-inclusive mother of all wrap-in-block functions'). > > To check it out, you need to > 1.
