[Jprogramming] A tale of two nouns

[Ric Sherlock]

I can't reproduce your results above in a clean J7 session.
   f=:i
   nc <'f'
3
   g=:j
   nc <'g'
3
   h =: blah
   nc <'h'
3
NB. The interpreter appears to assume that an unassigned name is a verb
that has not yet been assigned.

   blah=: *:
   h 3 4 5
9 16 25
