File Reference Table for Batch Importing

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.
Note: This information can also be found in the SASHELP.GISIMP data set. See The SASHELP.GISIMP Data Set for more information.

For the SASGRAPH and generic import types, which require that the spatial data be stored in a SAS data set, 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.
