Dear J Forum,
I'm working with an array of n items. It's possible for my index to be _1;
but then I'd like _1 { array to generate an error, rather than to select the
last item. Is there any "clean/elegant" way to do this, i.e., with just
using '{' and no conditional statements? I might have a similar problem
with i. _1. Thanks.
