Thanks Henry, Raul and John for the helpful comments. The following script reproduces the problem. It seems to only occur when the verb has a boxed argument. The box characters below may not reproduce correctly.
t1 =: 4 : 0 INFO_base_ =: 0 2$0 sel^: (>:i.x) y. ) sel =: 3 : 0 'r s' =. y. v =. (>:r), 1.1*s INFO_base_ =: INFO_base_ , v <"0 v ) 2 t1 1;2 ???????? ?2 ?2.2 ? ???????? ?3?2.42? ???????? INFO_base_ 2 2.2 2 2.2 3 2.42 Taking the Dictionary sentences refering to scalar n and to array n, one would expect the verb to be evaluated exactly n times for both n and ,n. Whether the data is a boxed array or not should not modify that expectation.
