<y is an atomic encoding of y ,
as discussed in Section II A.
The result has rank 0, and is decoded
by > .

|
x<y is 1 if x is tolerantly
less than y . See Equal (=) for a definition of
tolerance. <!.t uses tolerance t .

Boxing is also effected by verbs such as Link (;) and
Word Formation (;:):
(<'abc'),(<5 7),(<i.2 3)
+---+---+-----+
|abc|5 7|0 1 2|
| | |3 4 5|
+---+---+-----+
;: 'Now is the time'
+---+--+---+----+
|Now|is|the|time|
+---+--+---+----+
] a=: 2;3 5;7 11 13
+-+---+-------+
|2|3 5|7 11 13|
+-+---+-------+
>a
2 0 0
3 5 0
7 11 13
Cut (;.) with < has several uses
(chosen by the right argument); the phrase <@v avoids
the padding (and some domain errors) that may result from
applying v alone:
<;._1 '/i sing/of olaf/'
+------+-------++
|i sing|of olaf||
+------+-------++
i."(0) 2 3 4
0 1 0 0
0 1 2 0
0 1 2 3
<@i."(0) 2 3 4
+---+-----+-------+
|0 1|0 1 2|0 1 2 3|
+---+-----+-------+
If y is a high-rank array, <"_1 y
or <"_2 y often gives a more intelligible
display than y itself.
The display of a boxed array would normally be corrupted by
control characters (such as carriage returns and linefeeds)
occurring therein; in the display such characters are replaced by spaces.
For example, try < 8 32 $ a.
