With Guile 1.8:

  $ guile
  guile> (help open-input-file)
  `open-input-file' is a procedure in the (guile) module.

  Takes a string naming an existing file and returns an input port
  capable of delivering characters from the file.  If the file
  cannot be opened, an error is signalled.
  guile> (help open-output-file)
  `open-output-file' is a procedure in the (guile) module.

  Takes a string naming an output file to be created and returns an
  output port capable of writing characters to a new file by that
  name.  If the file cannot be opened, an error is signalled.  If a
  file with the given name already exists, the effect is unspecified.
  guile> (procedure? open-input-file)
  #t
  guile> (procedure? open-output-file)
  #t

Both procedures are bound by default.

Which version of Guile are you using?

Thanks,
Ludovic.
