Roger responded: > Please explain why this is not permitted by J syntax. I believe Ian is expressing a thought recently raised by Erling Hellenas in [1], which I responded to here: http://www.jsoftware.com/pipermail/programming/2014-July/038030.html -Dan [1] "J and indexed replacement": http://www.jsoftware.com/pipermail/programming/2014-July/038068.html "In most languages indexed replacement is indexed replacement? In J and in most functional languages it is not? You get a brand new variable? So, why give the user the flawed impression he can still do indexed replacement and do amendments to variables/nouns? And at the same time in tacit code we pretend to only have functions? No variables/nouns to be amended? Just functional transformations?" ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
