Is there any way to open a file whose name is written in another file? For =
example, I want to open file A in emacs. The path and name of file A is rec=
orded in file B. The filename of file B is fixed, but file A is changeable.=
 So I hope emacs can read the path&name of file A in file B first, and open=
 file A.
