Please note that the Aurora Text Editor is no longer sold and no longer supported by its author/owner (NText). The shareware version of the editor is still available at several shareware archive sites and at this site (both the last DOS release for 8086 and 80386+ processors and the Win32 console mode beta version). You can still use the program and below you will find a way to register Aurora32 (provided by Aurora's creator), the Win32 command mode version of Aurora, which still runs, even on XP and Vista. What you find here are my own personal experiences and opinions as a registered user of this software. My ability to help assumes I have the time and the necessary knowledge (usually I do). --KN

DosBox 0.72 will run Aurora 3.0 (DOS) quite nicely on *nix systems. See the DosBox web site where you can find versions of DosBox for Windows, Mac OS-X, several Linux distributions, FreeBSD, OS/2, and several other operating systems. Also there are some tools and language add-ons there.

A couple things to note: one is that DosBox limits you to 63Mb of memory, so this would constrain the size of file you can edit. Another is that you are emulating DOS, so depending on the speed of your computer, the performance may not be fantastic. But, it is one way to enjoy Aurora in a *nix environment. (Aurora 32 will not run on a DOS system, emulated or otherwise. For running Aurora 32 on *nix consider running it in Wine.).

Here's a tip someone sent for registering Aurora, which seems to work for any version of Aurora (old or new).

    * Either in the Macro pull-down menu pick "Macro Expression" or if you have not changed the default key map to something else hit Alt-F12 to get the Macro Expression command line (or however you get to a Macro Expression command line, which may be different depending on the keyboard mapping scheme you've chosen).
    * Enter:

          xE "Your Name" 

      where Your Name is the name you want to use to register and hit return.
      Note that your name must be in quotes. xE is a macro in the default Aurora library and not something you need to create, obtain, or modify.
    * Exit Aurora and start it back up. Your name should be registered. 

This is quite interesting because it does not require any tools to implement other than Aurora itself.

Jeff has kindly sent a way to run a registered version of Aurora32.

Here is the pertinent information:

"...the .bat file command I use to register is:
ac -reg "Jeff Wunderlich" "xujcwpkgzngqmqn" 1
Feel free to share it with anyone on the net."

Also, see http://www.transmuter.org/index.html which is about a programming language called Trans that Jeff is developing for x86 Linux and x86 Win32.

Thank you Jeff! --KN 09/07/06

One note from a user who tried the above: if you can't get the registration to work, try running the batch file in Win98 compatibility mode. I used a batch file (.bat) with a name different from ac.bat and the contents above, in the same directory as ac.exe. Running that batch file under Win XP SP2 successfully registered Aurora32 for me, without using compatibility mode. Running the "ac -reg" command from the command line did not work for me. Your mileage may vary. KN, 10/07/07
