I've enlisted myself to update the fractals labs. I notice that some
of the sentences do not evaluate, or show when running the lab. (jgtk
front end). For example to make the pentagon draw I must intersperse a
few extra lines of smoutput:
Now try drawing a blue hexagon (6 sides) before continuing the lab.
)
gdopen ''
smoutput''
RED gdpolygon ,+. r. 2p1*(i.5)%5
smoutput''
gdshow''
smoutput''
The sentence somewhat before this (probably) evaluates but does display:
load 'graph viewmat numeric trig'
I investigate the pervasive quality of this trouble by comparing the
outputs of the Introduction to J lab under jwd and jgtk. Sure enough,
they differ. The substantial difference is this:
jgtk, the sentence 2+3 is missing.
To clarify ideas, enter your own experiments (which you may
do at any point).

I presume that labs.ijs needs modification. I'll look into it, but
someone else is probably a lot faster.
Thanks, Dave.
pacman labs up to date.
