Erro ao criar TRIGGER

Olá pessoal,

estou tentando criar uma trigger e o seguinte erro acontece:

Dynamic SQL Error
SQL error code = -104
Unexpected end of command
Statement: CREATE TRIGGER tI_prc_parcela FOR prc_parcela AFTER INSERT AS
/* ERwin Builtin Wed Aug 27 20:12:02 2003 */
/* INSERT trigger on prc_parcela */
DECLARE VARIABLE numrows INTEGER


o código para criação das TRIGGER é:

CREATE TRIGGER tD_prc_parcela FOR prc_parcela AFTER DELETE AS
/* ERwin Builtin Wed Aug 27 20:12:02 2003 */
/* DELETE trigger on prc_parcela */
DECLARE VARIABLE numrows INTEGER;
BEGIN
/* ERwin Builtin Wed Aug 27 20:12:02 2003 */
/* vnd_venda R/7 prc_parcela ON CHILD DELETE CASCADE */
delete from vnd_venda
where
/* OLD.vnd_id = vnd_venda.vnd_id and
OLD.vnd_tipo = vnd_venda.vnd_tipo */
OLD.vnd_id = vnd_venda.vnd_id and
OLD.vnd_tipo = vnd_venda.vnd_tipo;
