Hi Gilles,
When I comment out the definition of mean and then clear the base locale and
run with debug on I get the following in the top pane of the debugger I get 59
lines with a '>' indicating line 41 (would be simpler if I could copy the
results that show up in the pane but don't know how).
In the second pane I get:
value error
Fold_j_[41] 13!:8 ] 13!:11''[FoldZv_j_=:fzv
trajectory[0] u F: v y
script[0] {: 3 : '0!:0 y [ 4!:55<''y''' jpath_z_&.:>
fn[tacit] script
load[7] fn fl
load[0] 0 load y
I am not sure how to interpret that, but is the result that I get. I am running
it by loading a script with the definitions and final line:
plot trajectory U
I get the same result running that line in the Qt IDE
And now the debugger has become non operational. Buttons do highlight, but do
not do anything and the debugger will not clear or exit. The script window can
be edited and loaded but the execution window only responds with the load
command and does not update. Toggling between windows does not include the
debug window, although it can be selected when clicked on.
Hope this helps!
Cheers, bob
