Hi, (info "(guile-1.8)File Ports")
-- Scheme Procedure: open-input-file filename Open FILENAME for input. Equivalent to (open-file FILENAME "r") -- Scheme Procedure: open-output-file filename Open FILENAME for output. Equivalent to (open-file FILENAME "w") These procs are found in ice-9 r4rs. The docs make no mention of this fact. Having found the procs, you'd expect (use-modules (ice-9 r4rs)) to work but it's broken. r4rs.scm doesn't even contain a call to define-module. Although: load-from-path "ice-9/r4rs" doesn't throw an error open-input-file and open-output-file are still not bound. Sebastian
