Open PL/I can be used with the IBM's DB2 database system. Open PL/I has a precompiler for embedded EXEC SQL statements in your PL/I programs.
While the DB2 precompiler can be invoked directly with mfdb2, we recommend that you invoke it with the -db2 option to the mfplx command.
Open PL/I's DB2 support is license managed. You must obtain a special license from Micro Focus to use it. Of course, you must also have IBM's DB2 product.
