Running Open/ed in maximum ED compatibility mode.

[Greg Field]

A few people I know are interested in running Open/ed in maximum ed compatibility mode. 

Here is how.

Install Open/ed. 

Find the install base directory :

1. /opt/OpenEd                         on Linux.
   
2. /Applications/OpenEd.app/   on OS X.
   

Under the base directory is a /bin sub-directory.

In here is the ned executable.

There is a hard link named ed.

If you execute ed, it will run in maximum compatibility mode, which is called OLDED mode.

It is important that you do not mix up this ed executable with the traditional Unix editor ed.

The best way to run it is with an alias in your .profile file (or bash startup).

 alias ed="/opt/OpenEd/bin/ed"

Then re-run your profile, or just login again.

I would do the former by 

 .  ~/.profile

•  Note the leading stand alone dot.
  
•  And the next character is the tilde '~'.
  

Then you can just use ed to bring up Open/ed in OLDED mode.
