Hello Rene Paul

compare

| res | res := OrderedCollection new. #($a $b $c) do: [:aChar | res add: aChar]. res

an OrderedCollection($a $b $c)

| res | res := OrderedCollection new. #($a $b $c) do: [:aChar | res add: aChar; add: $,]. res

an OrderedCollection($a $, $b $, $c $,)

and

| res | res := OrderedCollection new. #($a $b $c) do: [:aChar | res add: aChar] separatedBy: [res add: $,]. res

an OrderedCollection($a $, $b $, $c)

These comparisons are very enlightening. Thank you very much Stephane. -- All the best Rene Paul Mages (ramix) GnuPG key : 0x9840A6F7 https://sites.google.com/view/les-logiciels-libres/pharo https://twitter.com/RenePaulMages
