[Jprogramming] Release-a j807 problem with plot

[Ian Clark]

Yes, I can reproduce Joey's error on my nonavx Mac. (JVERSION is identical
to Joey's). But I do not have an avx machine to reproduce the whole of
Joe's test.

I reported a similar error with jqt, which has stopped me using plot with
j807.

However after I enter: dbr 1 (as Bill suggests), it cures the problem. Plot
now performs as it should do, with no suspension. This is the case with
both jcon and jqt in j807.

But when I now enter: dbr 0
…the problem returns.
