 ====== Default Editor ======
+EXEC provides two commands that invoke the default editor: **EDIT**, to edit an existing file, and **CREATE** to create a new file. The default editor is determined by the logical name **EDITOR:**. You can customize the default editor for all your log-in sessions by adding the following line to your LOGIN.CMD file:
+<code>
+@DEFINE EDITOR: SYS:EDIT.EXE
+</code>
+You can specify the executable file for any editor you wish to use in place of SYS:EDIT.EXE. On TWENEX.ORG, the following editor programs are supported to at least some extent:
+  * EDIT
+  * EDT
+  * EMACS
+  * TV
+You can check your current default editor with the command:
+<code>
+@INFORMATION LOGICAL-NAMES EDITOR:
+</code>
+//(The TOPS-20 User's Guide also documents a **PERUSE** command for invoking the default editor, but this feature is not supported on TWENEX.ORG.)//
