Firebird does not support such syntax. The closest solution is:

EXECUTE BLOCK AS BEGIN
INSERT INTO tbl_x(col1, col2, col3) VALUES(' val11 ', ' val1'2, val13);
INSERT INTO tbl_x(col1, col2, col3) VALUES(' val11 ', ' val1'2, val13);
/* ...and so on */
END

Note, the size of the SQL statement is limited by 64k or 32k in compiled
form (the smaller applies).
