Arggggggh. This is apparently not my week. I gave you this little
patch without even running the test suite. I'm sorry, everybody, for
the incredible stream of misinformation I've generated the last few
days!
To make this patch work, you also have to change line 96 in
Pattern.java. Change
m_slotLengths[i] = 0;
to
m_slotLengths[i] = -1;
I notice that the jess/examples/pumps/pumps.clp example file shipped
with jess50a3 lacks the final (run) command, so by itself it does
nothing.
