The goto statement unconditionally transfers control to the label following it. The label can be anywhere within the same procedure. It is in principle possible to jump into a block (e.g. loop body) from outside.

The return statement causes the executing procedure to return. If a return value is specified the expression is evaluated and returned as the return value of the procedure. If no return value is specified the procedure returns an undefined value.

Returning from a procedure automatically frees any resources associated with the procedure. This includes values in local variables or call by value (IN) parameters and any cursors that may be open.
