-
fileref
-
specifies the fileref assigned to the directory.
In a DATA step, fileref can be a character expression,
a string enclosed in quotation marks, or a DATA step variable whose value
contains the fileref. In a macro, fileref can
be any expression.
DOPEN opens a directory and returns a
directory identifier value (a number greater than 0) that is used to identify
the open directory in other SAS external file access functions. If the directory
could not be opened, DOPEN returns 0. The directory to be opened must be identified
by a fileref.
