    The subject says it all. Some time ago I read a message on SLUG on how
    to map from unit/surface/cyl/sect numbers supplied by e.g. an
    irrecoverable disk search error to the corresponding FEP file.
    Unfortunatly I didn't save it.

    Has anybody these three lines of code at hand (or in mind)?

I can name that tune in 1 line:

(si:get-file-containing (si:dpn-from-address unit cyl head sect))
