fout and flush -- Looks like the V6 version of cr3 - which is using the
portable C library which was done before the standard C library.
I bet if you grab the one from 2BSD that should have been updated to V7

https://danhalbert.org/more.html - mentions cr3
It makes sense that it used to be paper based and slow on screen.
Regarding the links and old bsd's. The binary cr3 on 1bsd works in v7.
Also, the book I'm reading has a c program that does paging. But, I'm
always off down the rabbit hole... I tried to compile the cr3.c source and
I get this error:
# cc cr3.c
Undefined:
_fout
_flush
_getc
_end
My understanding is that cc includes libc by default, so these must not be
in libc. But getc is standard lib, so what am I missing?
Thanks,
Will
