And you can use a fork in the definition of a conjunction:
of =: 2 : 'v@[ u v@]'
4 + of *: 5

A fork is not a conjunction but it shows what you are doing:
4 (*:@[ + *:@]) 5

It seems that I haven't been using Compose either :) . But at least I
knew that this is the place to be.
Thanks again,

I expect you'll get many of the same response. Your conjunction is
fine, however this particular case is so frequent there's a built in
conjunction. Read "but first",
x f&g y
or
x f&:g y
the difference being rank. Add but first square:
4 +&: *: 5

Hello everybody,
I realized with some shame that I haven't written a single J
conjunction - ever. Some adverbs, yes, but they too are newish.
I have a recurring need for sentences like (f x) g f y where verb f
is
applied to nouns x and y and dyadic verb g is then applied to the two
results.
and was thinking of something like x f c g y with c being a conjuction.
This is what was the result:
fxgfy=: 2 : 0
:
(v x) u v y
)
4 + fxgfy *: 5 NB. very simple example
4 + fxgfy *: 5
41
Is there a more natural J way to do this? What would be a good name
for
this type of conjunction or operation?
Esa
