I actually like ed and sam. I find it "soothing" to be able to manipulate text almost "programmatically"....

As an undergrad at USyd EE Dept, the VT100s in the computer lab were often all taken, but there were a few LA30s still hooked up and no-one wanted to use them. I learned how to optimally enter, compile and debug code through a paper interface. It was VMS of course at EE, but when I started using the Unix systems at CS a year later, the 11/750 was so heavily loaded that "ed" was the best choice for getting assignments done quickly. Line editors were also much more pleasant to use over slow modem connections. I had a 28.8k modem but the dialup pool rarely got you a high speed connection...

But back to the original topic... Has the MHSnet code made it into the public domain?

If you know the ex subset of vi, you know most of what you need to
know to use ed ...
