File Reference Table for Batch Importing lists the reserved filerefs for each of the different import
types, a brief description of each file, and whether the fileref is
required or optional when using that import type. For
example, to import a Digital Line Graph file, you must allocate the
file with a fileref of DLGIN.

SASGRAPH and generic
import types require that the spatial data be stored in a SAS data
set. Therefore, do not allocate a reserved fileref to indicate the
location of the data set. Instead, assign the name of the SAS data
set to the INFILE macro variable.
