Not to mention that it's long been a principle in the APL world that any
behavior giving an error can safely be given non-error behavior, though
this looks more like it's simply a bug in 8.05 that got fixed.

The original example was
(>1 0 1; 1 1 0; 0 1 1 ) #"_ 1 > 1 2 3;4 5 6
I think that Raul was using ; in place of # for illustrative purposes.
(>1 0 1; 1 1 0; 0 1 1 ) ;"_ 1 > 1 2 3;4 5 6 NB. J805

One of the 100 bugs fixed since 8.05.

Right -- that expression was for inspecting the arguments.
June Kim was getting a length error with # rather than ;
I had not intended to distract away from that issue.
Thanks

I see no reason for a length error.

Hello
I have been sticking with J805 for years. Today, I experimentally tried
J903 and found a significant difference.
