Wow, I never knew about this book, though I know ST and STP well, and used ST on RSX-11/M+ and VAX/VMS for $EMPLOYER in the 1980s.  Is the rest of the source code for the book available online anywhere?

Jez Higgins is rewriting the STP tools into modern C++.  His blog posts are at <https://www.jezuk.co.uk/tags/software-tools-in-c++.html> and the code is at <https://github.com/jezhiggins/stiX>.  He's rewritten the tools in chapters 1 and 2 and part of 3.

Since I find ed thoroughly unpleasant to use, having a screen editor was a must for me to use v7 for any length of time, and s fills that role rather nicely.

Gotcha.  I actually like line editors (you can't mung your file so thoroughly with a single stray keystroke), but I'm willing to trade a little standardosity for additional convenience, so I do almost all my editing of prose and programs in `ex`, occasionally dropping into vi-mode for matching open and close markers in Lisp and XML.
