Don't use the semi colon to run the commands, use SLASH. For example, the following does work

create type a
/
create type b as object ( attr1 REF a ) /
show errors type b

create type a as object ( attr13 b )
/
show errors type b

And will create the objects. NOTE that your attempt to declare B as an object containing A is invalid and will not compile. B can have a REF to A but not A itself (as A is not defined yet).
