Thanks Bill et al.
I think I have the beginnings of a workable connection. I can call JDo and
JGetM now, thanks to Jun Kim's script (with a couple of modifications).
One thing that is still failing, is trying to load a script through jDLL.
e.g. (added to previous python script)
run_jcmd("load 'j80
Did you load profile.ijs during booting?
Where is your working directory?
How do you verify script was loaded?

Here is the rule:
You may only insert one verb as many times as you wish anywhere in the
expression to produce the desired result:
3()4
3
3(%**%%*%)4
16
Here is the desired result:
3((***)(***)***)4

Here is the expression you must modify to gene

I believe 5!:4 < is a hook and that when you enter a verb train the
system simply echos it.

All you are allowed to add are J verbs without affecting the pattern:

I suspect you failed to load profile.ijs either. The J user

That was, of course, a j verb.

The sequence is: (5!:4 < "pace") so maybe it is a train or a trolley

Probably, yes.
And I was sort of provocative by not going with the implied limitations.
But there's can be quite a bit of ambiguity when key issues are
implied, rather than addressed or illustrated.
This is a problem I face myself, quite often: How can I be aware of
important issues which matter
Another way to do the same thing, but not a solution, is this expression:
3 (*(*(***)*)*) 4 NB. Funny way

Anyone can find a nice recursive way to write it? My best shot:
12 1:`([ * [ $: [: <: ])@.([: * ]) 8 NB. Complicated way

It's a recursion? * $: *

completely off topic, but would it be a good or bad thing if, assuming there
was a shortage of ascii mnemonics, and some need, if monadic +: and *: were
redefined considering that +~ and *~ do the same?

The issue occurs when your verb causes side effects. The problem occurs by
calling the unwanted function even if its return value is "correctly" discarded.

Linda, does your tree display explain the difference for you?
I have tried to show what I mean with trees. The only word that may be
missing is "isolated": Trains are isolated sequences of verbs, and
parentheses pairs can induce isolation. In the first example the first 3

Brian, This looks good. Sometimes I succeed sometimes not. I think the best
way to get trees to work is to paste from VHS and then either use Options and
