Sorry about that Henry, I have updated now.
On the last run, I ended up having to go into the Activity Monitor to force
quit the J process.
When I reopened the session, I updated the addons (including base) and
restarted and the reloaded the project that the trajectory script was in. When
I loaded that script the first time:
load '/users/bobtherriault/j901-user/projects/enhanced/jig6.ijs'
|fold limit: trajectory
| u F:v y
|[-346] /users/bobtherriault/j901-user/projects/enhanced/jig6.ijs
Subsequent loading of the script results in everything running smoothly even
after executing clear '' plots display as expected
Loading with mean commented out and debug off I get
load '/users/bobtherriault/j901-user/projects/enhanced/jig6.ijs'
|value error: trajectory
| u F:v y
|[-346] /users/bobtherriault/j901-user/projects/enhanced/jig6.ijs
Turning debug on after executing clear '' of course revealed no verbs in the
base locale. Loading the script again caused J to crash ( I can send the crash
report if that is useful)
Restarting J and running the script I once again get the expected:
load '/users/bobtherriault/j901-user/projects/enhanced/jig6.ijs'
|value error: trajectory
| u F:v y
|[-346] /users/bobtherriault/j901-user/projects/enhanced/jig6.ijs
Then I clear '' and this time load the script first and then start the debugger
(the default is trajectory). Loading script crashes again ( crash report saved
for this one as well)
Let me know if you want the crash reports.
Cheers, bob
