EXIT CASE statement terminates the execution of a WHEN clause or an OTHERWISE clause and passes program control to the first statement following END CASE keywords. 4GL skips any statements located between EXIT CASE and END CASE keywords.
END CASE keywords define the end of the CASE statement; they must be placed after the last WHEN clause or after an OTHERWISE clause, if it is included.
For more details on the END CASE and EXIT CASE keywords, see the END statement and EXIT statement.
