\typein
asks for input on run. While running the unmodified file, you'd get the following question:
Enter file names to process, (chap1,chap2 ...), or `all' to process all files:
\files=
At this point you'd have to enter all
to include all files.
If you always want to include all files, replace this:
\typein [\files]{Enter file names to process, (chap1,chap2 ...), or `all' to process all files:}
with this:
\def\files{all}
This way you can always change the included files by changing the definition. It for some reason you'll never do that you can remove (or comment out) this part entirely:
\typein [\files]{Enter file names to process, (chap1,chap2 ...), or `all' to process all files:}
\def\all{all}
\ifx\files\all \typeout{Including all files.} \else \typeout{Including only \files.} \includeonly{\files} \fi
