The J parser is unambiguously defined by the online webpage dicte as
pointed by Raul, or page 80 in my previous image. It is quite simple.
Please state which part you couldn't understand.
I am curious, you seemed to have written a simple version of J interpreter,
how was it possible without knowing the J execution stack model in page 80?

Hi all!
As I see it there are two ways to handle a dyadic verb in a parser. Either
you react on the trident N0 V1 N2 or you partially execute V0 N1. In this
case the product must be a new monadic verb. This new monadic verb is then
handled further in the parse process. However, I can not see any verb
results of V0 N1. This means I don't understand how the parser could
execute a dyadic verb(like in explicit J) or how it could compose the
dyadic verb with previous compositions (like in tacit J).
According to my analysis handling N0 V1 N2 as a trident would be much more
efficient, since the other alternative would be to execute each verb twice
or compose it for later execution twice.
It seems in J partial execution of dyadic verbs is not possible since the
monadic form of the verb would then be executed and the left noun argument
would cause a syntax error.
Maybe Bill or Raul can in clear terms describe how the parser handles
dyadic verb application so that we can put an end to this very strange side
discussion?
Cheers,

Or it looks like I was incorrrect, in terms of the thinking that went
behind it.
Even though the noun train would not handled as a trident by the
parser, it looks like Ken had that in mind as a part of the structure
of the implementation.
Thanks,
