This should be the final beta before the release of Doors CS 6.1. Most of the improvements have to do with the new in-shell editor. The Editor feature is now properly limited to BASIC programs and deals correctly with archived and/or locked programs. Goto is now completely instantaneous and understands subprograms. Several other stability issues have been dealt with, most involving the CALCnet2 networking subsystem. In the documentation arena, the manual has been updated to address the new features and interface for several areas of the shell. Check it out and report back! If you experience any issues with the editor, a RAM clear and if necessary an appvar purge usually does the trick.
