Let's try again, with line-throws this time. I forgot Thunderbird (or
something) messes up my J copies. Sorry!
annmatch=: 3 : 0
NB. this default monad call assumes existence a global bals
bals annmatch y
NB. following colon ":" separates monad & dyad sections
:
NB. this is the start of the dyadic section
NB. next line uses the x input/argument
bals =. x
countmatches=: a: NB. you could keep this local by the alternative
(next line)
NB. countmatches=. a: NB. ... unless you need the array after return
NB. rest as before
)
Alternatively, you can create the dyad with 4 : 0 (or dyad : 0) as follows:
annmatch=: 4 : 0
NB. don't include the single colon ":"
NB. next line uses the x input/argument
bals =. x
NB. the rest as before
)

3 : 0 (or indeed monad : 0) defines a monad by default,
but may be used to create both; try for example
... [see layout in new post above]
I expect you'll get many other helpful replies once they wake up
stateside (and elsewhere!)

Hi guys I have the below verb annmatch and would like to make it a dyad
the noun bals is what I want to replace with an X value so I can make
this more flexible and not tied to bals ; just not exactly sure how to
go about it ; hope I'm making sense and using the appropriate j-language
here.
Any direction would be appreciated
annmatch=: 3 : 0 countmatches=: a:
for_a.
y
do. countmatches=: countmatches,(<( {: /:>(+/ each a e. each bals)))
end.
}.countmatches
)
thanks
John
