I have some doubts about []MAP and []XT My goal is to park -for a subsequent possible reuse- many temporary numeric arrays (mean []SIZE is 0.5M) obtained during the processing of a long procedure, . I envisaged to exploit mapped files or extenal variables Is []XT obsolete with respect to []MAP ? or ...

I don't think NaNs are necessary nor are they a good idea. In all the places I have seen them in use (typically missing values in timeseries) it was easy to produce code to handle NaNs by faking them with special values not seen in the data. In one place I worked we had special user defined ...

I am looking forward performance in my code. I met a situation that I cannot explain to myself.

sometimes is not able to do its work.

e.g. try the following in a CLEAR WS:

      ]display ⎕STACK

      Here is a simple repro:

      {{⍬∘⍴∘⍴¨⎕lc ⎕si ⎕stack}⍵}0    ⍝ should return 1 1 1
 1 1 2

I think that 1 1 2 is correct.
In fact ⎕STACK must contain a second row related to "desk calculator level".

Do I miss something?
