Dear All,
I've heard it said that you don't understand a subject
unless you can explain it to a computer. With that in mind
I've attempted a software implementation of Gustafson's Unums 2.0
( http://www.johngustafson.net/presentations/Unums2.0.pdf ).
If anyone is interested, there is a demo ava
Apologize to re-opening this old thread. I tried Joe's
patch on the current J source and it seems working. But
it also crashed when running g640 in the test suite.
I can get a simple repeatable expression that caused crash.
?@:(5e3&$)"0 ] 2
but 1e3 or 2e3 is ok. Any idea?

1. Downloaded www.learningj.com/unumslab.zip
1a. Unzipped file to: C:\Users\Skip\j64-804-user\projects\unum
2. Checked to make sure J labs was installed (and up to date)
3. Started a JQT session
4. typed cd 'projects\unum' in JQT session:
cd 'projects\unum'
|domain error: cd

project
You can try
1!:44 '~projects\unum'
instead of cd in your JQT session.

Or you can open the Lab dialogue in jqt with Help|Studio|Labs... and then use
the Browse button in the upper right to go to the unums.ijt file in the
unumslab folder. At least that works in the Mac system for jqt.

Robert,
Starting the labs, navigating to my unum directory, and then running lab
_jlab_ 'unums.ijt' worked! Now I'm able to run Roger's unum lab code.
Thanks for the help.
It looks like in my JQT, the verb "cd" is set to the foreign 15!:0, which
is a DLL call. I have no idea what this is so. Ther
cd is defined as part of the base system.

chdir would be 1!:44 if it were defined.

Well, I got a bit further in the unum lab, but it looks like I still need
to set the directory.
After a couple of steps in the unum lab I get:
load 'utils.ijs' NB. utility functions
not found: C:/Users/Skip/j64-804/utils.ijs
|file name error: script
| 0!:0 y[4!:55<'y'
So I still need to poin
use jpath on a '~start\directory' to convert it to something the rest
of the system can use.
Thanks,

Also it is 1!:44 not 1:!44 . I think 1!:44
'C:/Users/Skip/j64-804/projects/unum'
should do the trick.

Vijay,
'C:/Users/Skip/j64-804/projects/unum' worked, except it was really:
'C:/Users/Skip/j64-804-*user*/projects/unum'
Now I was able to get all the way down to lesson 6, when I got this error:
] smallpos =: SFJN 0.5
|value error: first
| a=.y>: (first@:>)"0 UNUMS
So it looks like "first
I also had similar problems. I think you'll also have to do
load 'general/misc/fndef'
to get definitions that are used in the lab. I load this before I do the
lab_jlab_ 'unums.ijt' listed in the readme file.
HTH,
Vijay.

In the readme, it said
... jconsole doesn't support labs
This is incorrect. One can run labs on jconsole
and type labrun_jlab_ '' (and up arrow to recall)
to advance.
