Editors

There are several editors available on VMS.

EVE:

The default editor on VMS today.

Activated by:

$ EDIT fnm

Relative little functionality out of the box, but very easily extendible. It is developed in a language called TPU and the full TPU sources of the editor comes with VMS.

EDT:

The default editor on VMS in the old days.

Activated by:

$ EDIT/EDT fnm

Operates in 3 modes: line mode (can be used for batch editing), nokeypad mode (similar to VI) and keypad mode (normal fullscreen editor).

LSE:

An extension to EVE supporting programming languages (LSE = Language Sensitive Editor).

Activated by:

$ LSE fnm

Very smart back in the 1980's. The language support is completely outdated today.

More exotic:

Editors like JEdit, Emacs and VIM also runs on VMS.
