[Jprogramming] Atop gerunds in J601c

[Cliff Reiter]

I updated to the latest J6.01c and discovered that the image3 addon
(beta updated to J601, see my message 9/21 in J general)
no longer runs. It seems compostions with gerunds are no longer
supported. I don't recall this being discussed in the forums (although
I admit I have been overwelmed by the traffic at times) and it was
more of a change then I expected between J601a and J601c. A simple
illustration (the image addon example is richer :))

J601a:
    9!:14''
j601/2006-09-04/09:20

    9!:14''
j601/2006-11-17/17:05
    ]@(]`])

There are easy work arounds, but I am curious as to whether this change
is a bug or feature.
Best,
Cliff
