The CHEF Editor

CHEF is a portable text editor written in BCPL. It is a descendant of the UNIX system editor ED, but has a significantly different command structure and a number of new features.

The primary field of application for CHEF is computer source program editing. However there are some simple word-processing facilities in the form of text justification and centering which make it usable for document and letter preparation. In fact, this document was prepared using CHEF.

The editor is 'safe' in the sense that the entire file is copied into an internal workspace before any editing takes place. The original file is undisturbed until you explicitly request that it be updated.
