Simple items within the array aredisplayed as above. For non-simple items, this rule is applied recursively, with onespace added on each side of the enclosed element for each level of nesting.Examples1 2 3⍳3⊂⍳31 2 3⊂⊂⍳31 2 3('ONE' 1) ('TWO' 2) ('THREE' 3) ('FOUR' 4)ONE 1 TWO 2 THREE 3 FOUR 42 4⍴'ONE' 1 'TWO' 2 'THREE' 3 'FOUR' 4ONE 1 TWO 2THREE 3 FOUR 4Multi-dimensional arrays are displayed in rectangular planes. Planes are separatedby one blank line, and hyper-planes of higher dimensions are separated by increasingnumbers of blank lines. In all other respects, multi-dimensional arrays are displayedin the same manner as matrices.
