Hi Ian,
I just tested the Averages lab on j701 and PREPARE seems to work, so I guess
that genie is out of the bottle.
I would use this facility to allow the learner to focus on the specific lesson
rather than the set up details.
In this way the ability to hide information is one of its gifts
I copied the behaviour from Oleg Kobchenko who I think was one of the
early adopters/designers of the JAL.

I 80%-agree with you. If zulu-lite and zulu-bare earn themselves no
friends, then it's the way to go. Mind you, I can do that now, exactly
as you say, and not disturb the foundations of zulu-lite or zulu-bare.

Thank you. It's all been copy/pasted from the Lab, but I admit it does
look prettier. The Lab lacks text formatting, but it does do the work
for you, so avoidin
Mac "Spotlight" shows me several Labs in j602 base libraries have
PREPARE-blocks, eg lapack.ijt -- I count some 40 others.
I may be adopting an unpopular stance here, but having only yesterday
discovered this facility, I don't like it, and wouldn't commend its
use. It's sneaky. And I don't accept
Hey everybody,
In J602 there was a markup Instruction used in labs called PREPARE that would
bracket J commands to allow you to do things behind the scenes when running a
lab file .ijt
I wonder if this would be an option to have scripts load without having the
learner aware of it. I think t
I see now that my description of "open" applies more to "matrix" and
is thus all wrong.
I like the wiki presentation much more. In addition to content
changes, the formatting on the wiki is really richer than the J pages.

Thanks, Brian. I'll mull over it for a day or two. It's certainly
grist for the mill.
As Raul points out, I need some pithy "blurb" stashed away in the
right places. When the dust has settled (and I have some 3rd-party
users) I'll be able to see clearly where, and what.
I was hoping to rely on th

Yes that's a typo. Should be Stringlist Conversion Package.

After looking

Lab for zulu totally rewritten. Splitting it into chapters was the answer.

That is very clever. I don't think I have ever seen or thought of

P.S. if you want to overtake (instead of length error when the right

One thing that has occurred to me is that in the early J Phrases
document, they referred to certain nouns as "specimens" and maybe your
nouns could build on that framework. Now that I am reminded that zulu
is a phonetic name, it does not seem so bad, but until I perused your
work, my only associati

The inserted empty boxes do not contain the correct shape and type,
which should depend on the cut verb (< here).
