Re: [Bug-apl] Formatting of large arrays

[Juergen Sauermann]

Hi Elias

like how?

One thing could be to set ⎕PW←1000 but that only avoids the indentation of subsequent lines.
Another way is to X←⍕BIG_MATRIX and then use ↑ and ↓ to display pieces of X. Another simple
trick is to ⍉ the dara before ⎕CRing it.

The general problem is that the way APL2 prints its output has been around for very long, already
since APL times, so changing it today will certainly confuse a number of people (including myself).

When printing a one-dimensional array which is wider than ⎕PW, and using a ⎕CR mode which uses box-drawing characters such as 8 or 29, the output is quite unreadable.

For example, with ⎕PW←89 (standard for my Emacs session) this is what I get when printing ⍳100:

      29⎕CR ⍳100

There must be a way to primat this in a nicer way.
