The ODS HTML statement opens the HTML destination and creates HTML output. The output from PROC TABULATE goes to the body file. FRAME=, CONTENTS=, and PAGE= create a frame that includes a table of contents and a table of pages that link to the contents of the body file. The body file also appears in the frame.
