13.35 GOTO Statement

The GOTO statement transfers control to a labeled block or statement.

If a GOTO statement exits a cursor FOR LOOP statement prematurely, the cursor closes.

Restrictions on GOTO Statement

• A GOTO statement cannot transfer control into an IF statement, CASE statement, LOOP statement, or sub-block.

• A GOTO statement cannot transfer control from one IF statement clause to another, or from one CASE statement WHEN clause to another.

• A GOTO statement cannot transfer control out of a subprogram.

• A GOTO statement cannot transfer control into an exception handler.

• A GOTO statement cannot transfer control from an exception handler back into the current block (but it can transfer control from an exception handler into an enclosing block).
