ENDSUBMIT ;
You can use the ENDSUBMIT statement in conjunction with the SUBMIT statement to submit SAS statements for processing from within a SAS/IML program. All statements between the SUBMIT and the ENDSUBMIT statements are referred to as a SUBMIT block. The SUBMIT block is processed by the SAS language processor.
If you use the R option in the SUBMIT statement, you can submit statements to the R statistical software for processing.
The ENDSUBMIT statement must appear on a line by itself. There cannot be any space between the statement and the trailing semicolon.
See Chapter 12: Calling Functions in the R Language, and the documentation for the SUBMIT statement for details and examples.
