Aucb.196 fa.editor-p utzoo!decvax!ucbvax!C70:editor-people Sat Dec 19 13:07:43 1981 My unix emacs >From ihnss!warren@Berkeley Sat Dec 19 13:05:37 1981 Since I am never really sure whether or not random mail into the arpanet will work from here, I thought I would publish this in editor-people for all of you who have asked me about my unix emacs.

Yes I have a unix emacs that will run on a shared I&D space pdp-11 without too much hassle. Unfortunately, Bell Labs has not, and probably will not release it to the outside world. My effort was not part of the "official" unix product, and thus is not likely to be included that way, and the only other way to get software released is to have it officially declared worthless, which seems equally unlikely. There are a lot of copies that have escaped, but unfortunately, if I want to keep my job I can't really have anything to do with them.

Sorry about this, If it were my choice, anyone could have it.

My previous conclusion was based on a record of all of the characters to pass through the interpreter of my emacs for a user community of about 50 users in 2-3 months. Breifly, they broke down as.

Insertion: 52% Control-char commands: 27% Prefixes (^X,^[,^U): 9% Meta commands: 6% Control-X commands: 6% (Note that sometimes meta commands get invoked without the prefix).

^F^B^N and ^P were 10-20 times more frequent than M-a,M-b,M-f, etc.

Of the commands, I could categorize them as:

Cursor movement: 20% Prefix: 18% Macro Programming (Control Structures, etc.): 15% Deletion: 12% Filess and Buffers: 4% Argument Specification: 3% Searching: 2% Others: 20%

I have no idea how specific this is to my particular installation, but most of those users were naive users who learned emacs as their first screen editor (or first editor period!).
