The DSPFD (Display File Description) command shows one or more types of information retrieved from the file descriptions of one or more database and/or device files. The information is provided for each file that has the specified name and that is found in the libraries named in the specified library qualifier to which the user has access. The information can be shown, printed or directed to a database output file (OUTFILE).
