Is this a Firebird 2.5 database with dialect 3 (if the database was created with InterBase before Firebird was born, it could be dialect 1, if it is a newer database it is most likely dialect 3 unless it is explicitly set to a different dialect)?

I created two tables (MACCOUNTS & SSALEINVOICEFOOTER), added the records you mentioned and ran the SQL through Database Workbench before I posted my reply, so the code ought to work. To me it seems as whatever tool you’re using to execute the query thinks that the semicolon actually ends the query rather than being part of the statement. You could of course try

SET TERM ^^ ;

before EXECUTE BLOCK, but I’ve never had to do that with EXECUTE BLOCK. I’m sorry that I’ve no other suggestion for you, if the database is not Firebird 2.5 with dialect 3 (OK, I jumped directly from Firebird 1.5 to Firebird 2.5, so I’m not certain whether it will work with older Firebird 2.x), then I simply don’t think my suggestion can help you.
