This was wrong.
Here's a working implementation of validIn:
validIn =: (<@(|~ #)"1 _ { ]) *. (|~ #)"1 _ -:"1 [
Example use:
(#~ validIn&(?5 5$2)) <:(#: [: i. */) 2+5 5

Thanks, Raul. Some of these changes are great.
A few aren't what I'm looking for though. One of the biggest is that while
my example happened to have steps with uniform length, I'd like my A*
program to work on arbitrary graphs, where a step from one space to another

There's a change I am tempted to make, but I think it would make the
code more complex.
So, instead, here's some "simplifications":

I put up a slightly modified version of this

Mostly, I replaced contains with e.
I keep thinking I made a mistake, looking at the diffs, but I think
that's a pastebin bug.
I imagine that it was stuck and not detecting that it's stuck.
Your new version worked (after I replaced g with exampleG on the last

I'm curious.
How do you use this? (What are some sample sentences.)

Turns out it works iff the colon is the first character on the line *including

The same turns out to be true for version 602. When I tested using version
602 I put the colon as the first character of the line, as is my habit, but
with leading whitespace the same error results.

Henry's version works for me in J701. There are relatively few engine
differences between 602 and 701. It is much more likely that there is a
typo or some human error. I suggest trying again and being very sure
everything is proper. Check the display of toy before trying to use it.
On Sat, Jul 7,
I have confirmed that Henry's solution works under J6.02 so this does
appear to be a flaw in J7

You defined a conjunction that produces only a monadic valence. Try
toy =: 2 : 0
:
z =: u v ''
x + y

Hello,
I'm getting a domain error when I try to invoke (the verb result of) a
custom conjunction. I think I boiled it down to this toy example:
toy =: 2 : 0
z =: u v ''
x + y
)
5 [ toy ] 7
|domain error
| 5[toy]7
Any help would be great. :)
