Of course, I also bring up important points which he ignores also. But, all of that still doesn't mean his point was unimportant. ISTM that older Forth standards would return the XT or equivalent (PFA) for ' (tick) if the word was found in the dictionary and/or vocabulary regardless of any execution semantics or immediacy etc. Therefore, *NOT* returning an XT for a word that's in the dictionary because it doesn't have any execution or interpration semantics would seem to be a departure from the prior Forth standards and/or historical Forth behavior. As Hugh noted, code which expects historical behaviors may break with ANS since ANS apparently made little to no effort to preserve such behaviors. I.e., his apparent claim that ANS code is non-portable would seem to be valid in the sense that the code would break on pre-ANS Forths. Although, I don't think he mentioned pre-ANS Forths anywhere in his claims. Rod Pemberton -- Just how many texting and calendar apps does humanity need?
