Subject IB 6.0 Yacc style Grammar
Author Ryszard Kubiak

While reading InterBase 6.0 DSQL Syntax, YACC Grammar notation,
I've found a few misprints. One of them is that blob_subtype
is defined twice in the grammar. I also think that
in the definition of alter_data_type_or_domain we should
have a reference to a domain and not to a column.

Best Regards,
