Here's a script dialog of "representation/copula". Run the script.
Note that there is no result for (x). Also I added x at the end which seems
to be worth including.

You are missing out on the more general notion of Atomic Representations.
Gerunds are arrays of verb ARs. ARs are uniquely defined for *any*
syntactic class, though, and you are free to mix them:
a =. +
b =. -
c =. /\
d =. 42
(ar =. 5!:1) ;:'a b c d'
+-+-+---------+------+
|+|-|+-+-----+|+-+--+|
| | ||5|+-+-+|||0|42||
| | || ||/|\|||+-+--+|
| | || |+-+-+|| |
| | |+-+-----+| |
+-+-+---------+------+
'`aa bb cc dd' =. ar ;:'a b c d'
aa
+
bb
-
cc
/ \
dd
42
nameclass ;:'aa bb cc dd'
3 3 1 0
(aa cc ,: bb cc) 1 2 3
1 3 6
1 _1 2

for 5!:1 (and, if you like, its reverse 5!:0); then re-read
<http://jsoftware.com/help/dictionary/d001.htm>
http://jsoftware.com/help/dictionary/d001.htm to re-check how the back-tick
in '`a b c' is defined.

parts with unicode box characters on the machine which receives the

The mailing lists send out emails in plain text format. For
best results, please send messages to the forum in this

When copying J session output to an email, first set
box-drawing characters to Ascii. The IDEs have a menu item
for this, e.g. in J8 Qt, select View|Toggle Ascii Box
