The consequences of placing an assignment at the close
of an explicit definition recently came to my
attention.
aa=:99
NB. no output produced when executed in J console.
se=: 3 : 'aa=:99'
se ''
99
NB. a verb must produce a noun.
So, it makes sense to return the last value handled
since verbs must both receive and emit nouns. What I
can't find is where this implied (]) may be
documented. I looked in the Dictionary under H. Frets
and Scripts and in Vocabulary under Copula. Where
should I be looking?
