Select SERIALIZE on the THREAD option of the PROCESS statement for multithreading support. Compiling with SERIALIZE prepares the ILE COBOL run-time environment for threading support. However, compiling with SERIALIZE may reduce program performance. You must compile all of the programs in the run unit with SERIALIZE; you cannot mix programs compiled with SERIALIZE and those compiled with NOTHREAD in one run unit.
The default option is THREAD(NOTHREAD). For more information about the THREAD PROCESS statement options, see THREAD Option.
