You can use Posix threads. 

Threaded jobs are intended to run ONLY in batch jobs (either BCH or BCI). 
Even though Qshell and Java applications are multi-threaded they aren't 
running in the interactive job. A BCI job is started and this is where the 
Java application and the various shell scripts and programs run. The 
associated interactive job is used simply to accept input and display 
output.

You can start your threaded application via SBMJOB and specify 
ALWMLTTHD(*YES) or use a job description that specifies ALWMLTTHD(*YES).

You can also spawn your threaded application using one of the spawn() APIs 
and setting the SPAWN_SETTHREAD_NP flag. This API will start a BCI job in 
which a threaded application can run.

Regards,
Simon Coulter.
