DINFO Function in
SAS Language Reference: Dictionary
|
DINFO(directory-id,
info-item)
|
-
directory-id
-
specifies the identifier that was assigned
when the directory was opened, generally by the DOPEN function.
-
info-item
-
specifies the information item to be retrieved.
DINFO returns a blank if the value of info-item
is invalid.
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 directory information items.
Use DOPTNUM to determine the number of directory information items available.
Under Windows, the only info-item
that is 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.
