Directories that are
opened with the DOPEN function are identified by a
directory-id.
Use DOPTNAME to determine the names of the available system-dependent
information items. Use DOPTNUM to determine the number of directory
information items available.
Under UNIX, the only
info-item available
is Directory, which is the pathname of
directory-id.
If
directory-id points to a
list of concatenated directories, then Directory is the list of concatenated
directory names.
