Finally I achieved persistence of all Logo nodes, so you can run any aUCBLogo program, close aUCBLogo, do something else, start aUCBLogo again and recover your last state. The last state can be running or in midst of a debugging session. This persistent mode can of course be disabled by unchecking "Autosave Nodes" in the File menu, which can be highly wanted if there are many users logged in with the same username.
Printing does now work.
Support for arbitrary precision math using the MAPM library has been added:
Andfor the debugging of the Garbage Collector (andfor my amusement) I wrote a memory window, accessable through the view menu, where one can inspect every Node by pointing with the mouse to it: a tooltip window with a textual representation of that Node will showup then. It's pretty interesting to see the GC working!
You can always ask me if you experience problems with aUCBLogo!
