Not sure I understand the name usage correctly. Are "Extended Oberon" and "Oberon-extended" interchangeable? https://github.com/andreaspirklbauer/Oberon-extended/blob/master/Documentati... gives error 404. "blob"should be "tree". Even so https://github.com/andreaspirklbauer/Oberon-extended/tree/master/Documentati... gives 404. Is the Streamlining document incorporated into something else? Moved elsewhere? Other complaints against https://en.wikibooks.org/wiki/Oberon/Oberon-extended ? Thx, ... P.L. - mobile: +1 778 951 5147 VoIP: +1 604 670 0140 https://en.wikibooks.org/wiki/User:PeterEasthope
