What's the problem? The script historico.sql has been executed with
sucess, but this error is genereated all times when I use the isql.
The commands of script has been executed in the database.

C:\sig_aluguel>isql dados.fdb -u SYSDBA -p dba1379 -i historico.sql
Expected end of statement, encountered EOF

historico.sql
CREATE TABLE CURSO (CURSO_ID INTEIRO_PEQUENO NOT NULL, NOME TEXTO_80
NOT NULL);
alter table CURSO add constraint PK_CURSO primary key (CURSO_ID);
CREATE GENERATOR GEN_CURSO_ID;
