The technical content
This is a conceptual overview to supplement the technical information in RFC-190. There is some stuff of interest in here, for example the author describes the display area that a program writes to as
"much like [...] a file which it has opened with write access". Strings written to the display are given unique identifiers, so that those strings can be manipulated (moved, deleted, replaced, changed) in-place.
A display can be subdivided into multiple display areas, so for example you could have a split screen view of text from different files at one time. Commands include things like “hortizontal split”, “vertical split” and “jump focus to display area”, which modern programmers who use programs like GNU Screen or tmux might be familiar with.
