Re: UNIX terminal io incompatibility



Unix isn't the only operating system with redirectable output.
(TOPS-20, believe it or not, does also; probably Tenex does as well.
.priin and .priou are similar to stdin and stdout.  The reason you've
never heard of it is that they couldn't figure out a decent exec
syntax.)

If one is going to attach *standard-output* and *standard-input* to
stdout and stdin respectively, *error-output* should be attached to
stderr.  I don't know about *trace-output*.
