It cannot be gerund or noun, for some reason the
magic flat indices work only for verb argument:
setb=: 1 : '(I.,m)"_}'
'#' b setb a
----##--#
#-##-##--
###--####
#--#-#-#-
-####---#
(a.{~65+i.+/,b) b setb a

Subject: Re: [Jprogramming] RE: }
Trying to generalize further, I run into a problem
because it seems that if a gerund form is used, J cannot
distinguish between m} and u} and assumes the m} form,
producing an index error. To me, if I am correct, J should
default to the u} form for gerunds.
13 : ' x #&, i.$ y '
[ #&, [: i. [: $ ]
loc =: [ #&, [: i. [: $ ]
b(('#'"_)`(loc"_)`])}a
|index error
| b (('#'"_)`(loc"_)`])}a
b(('#'"_)`loc`])}a
|index error
| b (('#'"_)`loc`])}a
(B=)

+ In this specific case is no need for special 'indexes' verb; i. will do just
