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.
