Hi Jürgen: Thanks so much for your patient help.
Being so out of date with modern APL I am completely “gob-smacked” (as the Brits used to say). Did not realize how much ⎕CR has been extended from the 1984 IBM APL 2 Language Reference Manual. Ditto for the 2000 ISO Standard. The elegance and beauty of the pure language, as extended, still remains. But to me the proliferation of ⎕ functions, useful as they may be, seem somewhat overwhelming. Do we really need all of them I wonder? Or are they just “it would be nice to have” things”? Oh well… I’m just a grumpy old man I guess…. respect….
