Firebird SQL Script command line limitation

Does anyone know if there is a command line size limit in Firebird?

When you run a small "insert" script it works fine, but when the script has a lot of strings, it returns the following code: "Unexpected end of command - line X, column Y"

.

The relationship, row and column number changes depending on the actual size of the script.

I am using Firebird 2.5

Here is the executable script:

set term ^ ;
EXECUTE BLOCK AS BEGIN
insert into TABLE (COLUMNA) values (13);
...
insert into TABLE (COLUMNA) values (14);
END^
set term ; ^
