Yes. It is defined in the web source.

Closing "write" files is different from closing "readfrom" files.

   All \ttt{readfrom} files that have not completely been read yet
   are closed\index{files!closing} automatically when the program
   terminates, but \ttt{readfrom} files can also be closed explicitly
   by using ${\tt closefrom}\ \descr{file name}$.%
   \index{closefrom?\texttt{closefrom}}
   It is wise to add explicit \ttt{closefrom} for files you do not need
   to read completely (i.e. until EOF is returned) because otherwise such
   files will continue to use internal resources and perhaps cause a
   \ttt{capacity exceeded!} error.
