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)

  ASSERTSYS(p<=zn,"jprx zn");

assertion can fail if original zv > 2*zu

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
