Can something like Script be done in System V?

If that's literally true, UNIX programs shouldn't go into (CBREAK/~ICANON)
mode and expect the system to act any differently.  Screen editors, however,
expect their input to be generated by a human being as they run; there's not
much point in running "vi" with its input coming from a program generating
commands or from a file consisting of commands generated by a program.  If
you want an editor that can either be driven directly by a person or by a
program, use "ed" - or "ex".  Screen editors solve a different problem from
"UNIX tools"; not all programs should be UNIX tools.  You can put a screen
front-end on top of an "ed"-style editor, letting the editor program run as
a "UNIX tool" and put the sane user interface in a separate process.
