Something confused me on the subject page. The shift right is only for a vector
and behaves differently for a matrix.
|.!.f says it will shift right 1, but when I tried it on a matrix, it shifts
down.

Has there been any consideration on providing the actual line number causing an
error on a script? Would be hugely helpful for newbies like me. Just a thought…

Duh…went to the About wiki page… apologies for the noise. Once I get a wiki

Is there a way to declare the rank when using {{ }} definitions? Or is it only

I wanted to learn to create a TextMate bundle so decide to not use the one

Is there a wiki page that documents the steps required to update J? I was
looking for it and couldn’t find it. I see the steps recommended in previous
posts but seems that would be a good addition to the wiki (unless I completely
missed it and if so apologies).

Is there a way to search the programming list archives? I keep finding
links here and there in the wiki of really interesting posts with J
code. Thanks, and apologies if I missed anything obvious.

Any plans to update the color reference card
“J602_RefCard_color_letter_current” to J902 or J903? I find the card pretty
useful for learning (actually I open it next to my editor for quick reference
on syntax) as the examples are sufficiently simple for me to understand. Some

Yea, got it. Thanks!

Needless to say, I expected 1 1 1. Any clarification/explanation much
