I made a typo on the name of the script file. It was jijx.ijs , Sorry about
that.
>From root/trunk/labs/labs/core/jtaste1.ijt is the section 19 which I
experienced the failure. There are 32 sections in this lab.
172 NB. =========================================================
173 Lab Section
174 The function +/ sums its argument. It is made up of + (add) with /
(insert), meaning insert + between each item of the argument.
175
176 So +/ 10 20 30 means: 10 + 20 + 30.
177
178 Similarly */ is "multiply insert", i.e. multiply all elements together.

I really stopped looking into what was happening when I saw that in lines
133 and 135 the script references a script file in the ~user library. I
can't see any reason why the J system code should look for or create any
specific script file in ~user. That's why I thought this might be some left
over testing code. What is '~user/projects/ja/ja.ijs'? Is it something that
is created temporarily? Makes no sense.
