The BREAK statement raises a runtime exception.
BREAK [expression ]
|expression||An optional expression to throw.|
BREAK throws a runtime exception, causing execution to branch to the nearest RECOVER, CATCH or FINALLY block in a BEGIN SEQUENCE-RECOVER USING or TRY construct. If execution is not within a BEGIN SEQUENCE or TRY construct, the application will terminate.
The specified expression will be evaluated and received by the nearest RECOVER USING statement, if any, as a value of type USUAL. If the nearest RECOVER statement does not have a USING clause, the result of expression is discarded.
If expression is not specified, it defaults to NIL.
LOCAL e AS USUAL
bar( 1 )
RECOVER USING e
? "An exception has occurred, exception value is:", e
FUNCTION bar( x )
IF Valtype(x) != STRING
BREAK "Argument not a string!"
