Bug Fixes
- Page setup didnt have any effect on printing — this should now work.
- Abort (Command-period) didnt work on very tightly recursive procedures — this should now be OK.
- After doing a lot of tracing, ACSLogo would fail with an obscure exception — this shouldnt happen now, but tracing might be a bit slower.
- The Output command would return unexpected object if it wasnt the last thing in a procedure. This has been fixed.
