aString splitOn: ' -_' asSet

Hello Richard, Thanks again , I find this "aString splitOn: '_- ` asSet " much cleaner but on some way I does not split for example 'Portable Network Graphics' into " #(Portable, Network, Graphics) ". When I debug it , it seems there is no splitting at all. So today time to dive into it why it does not work and how to solve it. Roelof
