You're right - I guess I must have changed that somewhere along the way.  The older version I was running produced integer, as did J6.02.  But I reckon my diagnosis is right.

I see what's happening.  1"_ produces a Boolean, while 1: produces an
integer.  In this case the Boolean is better.  I'm not sure whether it
always would be; what do you think?

Huh...

I can reproduce that 10x speed difference:

     timespacex 'c0 17'
0.078233 2.01328e8
     timespacex 'c01 17'
0.761976 1.61061e9
     c0
,@((1 0 1 */ ])^:(]`(1"_)))
     c01
,@((1 0 1 */ ])^:(]`1:))

This seems bizarre.

Thanks,
