You may unbinhex the file TEXT1_INDEX_SORT.BIN and run that application on a Macintosh (at least up to system 7). To create a new application on the Macintosh for the TEXT1 sorted index, you must TANGLE the TEXIX.WEB file (found in the directory TEXIX) with the TEXIX.TURBOMAC changes file. Then compile the program with Turbo Pascal on your Macintosh. It requires Turbo Pascal and Turbo Toolbox to compile.
