mksh-current from CVS comes with a shell function called “smores”
which implements “something like” more(1) in (Korn) Shell. You’ll
need to press Return though, not Space, to go on.

If you replace the word LINES with 15 you get the behaviour you
want. The source is here (just look for “smores”):
https://www.mirbsd.org/cvs.cgi/src/bin/mksh/dot.mkshrc?rev=HEAD

If your mksh is “too old”, you’ll need to replace
		llen=${%line}
		(( llen == -1 )) && llen=${#line}
with
		llen=${#line}
(since “${%foo} = width of $foo in screen columns” got added
only recently, but “${#foo} = size of $foo in octets” has been
there for a while)

Note that, if you run smores as shell function, it’s aware of
whether your current locale is UTF-8 or not (use “set -U” to
enable UTF-8 mode, “set +U” to disable it, if you don’t want
that). This, again, only affects ${%line} calculation.

Yay for having to rewrite other people's Bash scripts because bash
suddenly stopped supporting the bash extensions they make use of
