[Bug-apl] APL )DUMP/)LOAD bug - Nested Arrays...

[Martin R. Bartels]

Jürgen,

I looked through the bugs - I don't know beyond doubt that this is new, but FWIW, when attempting to create a "demo" nested array, it didn't survive the )DUMP/)LOAD round-trip.

The statements below will recreate it (on gnu-apl 1.6):

      a←2 3⍴'ABCDEF'

      b←3 3⍴⍳9

      c←○1

      d←'⍫'

      e←0

      f←⍳0

      g←7

      h←'Hello World'

      i←''

      j←3 3⍴a b c d e f g h i

      k←j

      k[2;2]←⊂j

      

       

      ⍝ ---Observe!---

      

      8 ⎕CR k

      

       

      ⍝ ---Now output/input---

      

      )DUMP xyzzy

      )LOAD xyzzy.apl

      

      ⍝ ---What happened to 2 3⍴'ABCDEF' at k[1;1] and the nesting at k[2;2]?-----

      

      8 ⎕CR k

 I hope that this helps!

Thanks!

——Martin
