Version 1.2

We produced version 1.2 in September 1992. Here are the features and bug fixes we added.

• Fixed problem with recognizing the tabular* environment.
• Excalibur is now System 7 friendly. It handles the required Apple events. (It handles the Print event, although it doesn't do anything.) As a result, it handles drag and drop operations properly. You may drag just one file at a time.
• Excalibur now uses a ``safe save'' technique for saving files if you are running System 7. That is, it saves the file into a temporary file. Once the save has successfully completed, Excalibur moves the file onto the original. This may make a difference if you are saving onto a floppy disk. Make sure there is enough room for two copies of the file.
• Excalibur now requires System 6.0.4 or higher.
• Excalibur recognizes the Apple extended character set.
• Fixed a display bug in the ``About the Authors'' dialog.
• Excalibur now recognizes AMS-LaTeX environments. In particular, it knows about the environments

  align	gather*
  align*	multline
  alignat	multline*
  alignat*	xalignat
  comment	xalignat*
  equation*	xxalignat
  gather	xxalignat*

• It knows the AMS-LaTeX commands

  accentedsymbol	numberwithin
  addtoversion	operatorname
  email	operatornamewithlimits
  eqref	series
  family	shape
  newmathalphabet	theoremstyle

• If Excalibur gets an error while trying to save a file, it tries to print a meaningful error message. If it gets an error for which it doesn't have a message, it prints the error number.
• Added Preferences File that saves spell-checking and dialog options as well as the names of active dictionaries.
• Changed Help dialog button from OK to Done.
• Added Text to Dictionary and Dictionary to text file conversions. Text files can be saved as MS Word, Alpha, or generic text files. Alpha contains some nice support for LaTeX. It's well worth the shareware fee.
