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Being so out of date with modern APL I am completely “gob-smacked” (as the Brits used to say).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….

Hi Peter,

the allowed boxing values are those in ⎕CR. Those can be displayed with

⎕CR ⍬

I have started to document all GNU APL functions and commands (some years ago),
but haven't made much progress lately.

Best Regards,

I ‘ve looked for documentation for these values but failed to find any.
And experimentation has also failed me.

Please direct me to it.
