TECO is a very powerful (and fairly easy to use) character-oriented text editor. The command line is: TEC outfile=infile or TEC file or TEC either or both "infile" or "outfile" may be omitted. The 2nd format is a normal edit/backup. The 3rd form takes the file-name from TECO's "memory" file---it edit's the file you editted last time. TES is TECO invoked in "split-screen" mode. The upper 2/3 of the CRT is a "window" into the file, and is kept updated. The lower 1/3 is where the commands go. There are also many special control keys which are extremely useful, especially in split-screen mode. See TECO KEYS. TES works on both the VT-100 and Hazeltine 1500.
