It might be a Linux thing.  Can other Linux users verify that

   9!:37 ] 0 256 18 20
   { 2 2 3 3;2 2 3 3;2 2 3 3

fails?

It doesn't fail on Linux. The error is probably that the emacs
mode isn't prepared for ... from J.

If so, does

   9!:37 ] 0 256 18 20
   4 4 4 $ 2 3 3

also fail?

Could I change this 9!:36 setting to get it to work?

Sorry, I don't follow. Can you show the problem with a simple testcase?

(The comments are mine but I didn't write the code)

With that setting of 9!:37, ({ 2 2 3 3;2 2 3 3;2 2 3 3) has one line
replaced by ... which is where the message comes from.

However, I can't make it fail.  I am running Windows.

FWIW, that system error occurs during formatting of long output.
What
do you get from executing

       9!:36''

?

I'm getting a very odd-looking error in both J 8.07 and J 9.01:
       { 2 2 3 3;2 2 3 3;2 2 3 3
jprx zn
|system error

Changing one number results in no error:
       ${ 1 2 3 3;2 2 3 3;2 2 3 3
4 4 4

Has anyone else seen this?  Can others reproduce it?

Thanks,

Devon
