The TSMODEL Procedure

The ENDSUBMIT statement is required to terminate the user-defined program statements in the PROC TSMODEL statement block whenever you specify the SUBMIT statement without the FILE= option. Do not specify the ENDSUBMIT statement if you specify the FILE= option in the SUBMIT statement. If you do not specify the FILE= option and you fail to include an ENDSUBMIT statement to accompany your SUBMIT statement, then the PROC TSMODEL step ends with an error.
