TheEditorRetro includes a block editor called RetroEditor, or red for short. This has been in use for many years, and has evolved into a simple, but very reliable, line-oriented editor. Various PortsOfRetroEditor exist for other popular Forth systems.
A visual extension, allowing for navigation and editing though the keyboard, has also been developed. This is called RetroEditorForMortals, or rem. For space reasons, rem is not included in the standard retroImage, but can be quickly loaded from the forthlets collection if desired.
Using The Editor
The editor is line oriented, so editing can be a bit tedious. Please note that all line and column numbers start at 0.
