Never mind, now I've got it; spxhtml and spxlatex are undocumented since they
are jhs only, and they are executed from within the NB. statements in the .ijs
script being executed, but not the copy displayed by the script in the edit

Fast append is no issue, appends can be very fast as you suggest. The issue is
to maintain an ordering attribute that is fast/custom for each use case (in my

Linked Lists work very effectively, although having said that I would not try

That's the lab that confused me. Spxhtml and spxlatex are in NB. comments, and
changing the arguments (in those comment lines, in the script display) does
nothing to change the outputs. Perhaps there is another copy of the script that
is running. Are the NB. Lines being run/interpreted?

Ah, nice -- thank you.
(Once I remembered to use osx command key instead of control key.)
Thanks again,

The spx.ijs script demos spx facilities and is specific to JHS.
The script to load the JHS 'simple project manager and related tools' is:
~addons/ide/jhs/sp.ijs
After the load, display sphelp and spxhelp for basic docs.
Many of the ideas of spx were merged into the latest version of labs. That

Yeah, I tried that example, also:

As I recall, you need to add one more directory level to /spx.ijs for the help
script. I'll check if I can reach my Mac mini at home.

But it's not clear to me how to load spx under jqt.
For example:
load '~addons/ide/jhs/spx'
|interface

Hi Jim,
I use it often, it is what is "under the hood" when you are running JD
tutorials using jdrt. If you fire up a JHS instance, there is actually a
tour of spx under "tour -> spx". It explains spxhtml and spxlatex in the
lab.

Fast append can be implemented on an array language without linked
lists -- the mechanism involves leaving some empty memory at the end
of arrays and using that for append when there's only one reference to
the array and that reference is being updated.
For multi-key indexing, what you would do i
I disagree on this point Devon, linked lists are a very powerful data structure
and can be “overlaid” atop dynamic arrays to maintain a desired index order.
Without such a structure the only practical way is to append and (re)sort to
maintain an array in a suitable form.
An example of this is t
Any users? (It's neat!) Any hints what's happening under the covers where
comments in spx.ijs refer to spxhtml and spxlatex (lines 48-57)?

For information about J forums see http://www.jsoftware.com/forums.htm
Yes, for J, you'd probably do something like (#/.~ trigrams), for a
batch of extracted trigrams. (Or something a bit more complicated, if
you allowed wildcard placeholders in your trigrams.)
And, if you had multiple batches, for example, from :
labels1=: ~.trigrams1
sums1=: #/.~trigrams1
labels2=
Perhaps not for betas, but the standard way updates are done for iOS/Mac App
Store updates? (I guess add ons would remain a special case?)

I used dictionary objects in Visual Basic (Access) to report similarity in text
strings based on trigram usage. The keys were the distinct 3-letter
combinations; the values were the incremented hit counts. It was both efficient
and effective. But I think there is a better array approach in J.
As je_update is already standard in current pacman, I assume you mean a
visible part of gui front ends to pacman. This is now possible and I expect
we will move to that.

A simple use case which resembles the German-English dictionary is to implement
variable-value bindings in a small interpreter. I've run into this many times
in what I've been doing lately.
