Assign the libref and the Web-server path. FILENAME assigns
the fileref ODSOUT, which specifies a destination for the HTML and GIF files
produced by the example program. To assign that location as the HTML destination
for program output, ODSOUT is specified later in the program on the ODS HTML
statement's PATH= option. ODSOUT must point to a Web-server location if procedure
output is to be viewed on the Web.
