So, it seems that you don't like PgUp and PgDn, and you don't like M-x
term RET. Then if you insist om M-x shell, you will have to write
your own pager that doesn't require a smart terminal (which shell is
not):
[pjb@galatea :0.0 ~]$ cat ~/bin/epager
#!/bin/bash
HEIGHT=${HEIGHT:=25}
eof=0
while [ $eof -eq 0 ] ; do
i=0
while [ $i -lt $HEIGHT -a $eof -eq 0 ] ; do
line=''
read line
if [ $? -eq 0 ] ; then
printf "%s\n" "$line"
else
eof=1
fi
i=$(( $i + 1 ))
done
read -p 'Press RET to continue, q RET to abort:' rep < /dev/tty
if [ "$rep" = 'q' ] ; then
eof=1
fi
done
[pjb@galatea :0.0 ~]$ cat /home/pjb/tmp/misc/wang | HEIGHT=10 epager

L'algorithme en question a ete publie en 1960 dans l'IBM Journal,
article intitule "Toward Mechanical Mathematics", avec des variantes et
une extension au calcul des predicats. Il s'agit ici du "premier
programme" de Wang, systeme "P".

Press RET to continue, q RET to abort:
existait, mais il ne s'etait pas encore impose) et l'auteur estime que
"there is very little in the program that is not straightforward".
Il observe que les preuves engendrees sont "essentiellement des arbres",
et annonce que la machine a demontre 220 theoremes du calcul des
propositions (tautologies) en 3 minutes. Il en tire argument pour la
superiorite d'une approche algorithmique par rapport a une approche
heuristique comme celle du "Logic Theorist" de Newell, Shaw et Simon (a
partir de 1956 sur la machine JOHNNIAC de la Rand Corporation): un debat
qui dure encore...
Press RET to continue, q RET to abort:
Cet algorithme a ete popularise par J. McCarthy, comme exemple-fanion
d'application de LISP. Il figure dans le manuel de la premiere version
de LISP (LISP 1, sur IBM 704 justement, le manuel est date de Mars
1960), et il a ete repris dans le celebre "LISP 1.5 Programmer's Manual"
publie en 1962 par MIT Press, un des maitres-livres de l'Informatique.
