Argument Type Description

fileref
C specifies the fileref to assign to the external pathname

pathname

Argument	Type	Description
fileref	C	specifies the fileref to assign to the external pathname
pathname	C	specifies an existing pathname to assign to the fileref. If pathname is blank or not specified, then the specified fileref is de-assigned.

Details

To assign a remote flat file on another host via the FTP-XX protocol, you must use the SCL FILENAME function. The _assign method will not assign filerefs to files on remote hosts.

Example

This example creates a SAS External File object, EXTFILE; assigns the fileref, MYFILE, to the external file MYFILE.TEXT; and then initializes EXTFILE to MYFILE:

extfilec=loadclass
         ('SASHELP.FSP.EXTFILE.CLASS');
extfile=instance(extfilec);
call send (extfile, '_assign', 'MYFILE', 
           'myfile.text');
