I see Bob Crothers has provided a good explanation of "worker threads" but
as a beginner you will need a good reference.  AS/400 threads are kernel
threads and implement the Posix thread model.  Get a good book on the
subject.  The one I use is:
        Title:          Programming with POSIX Threads
        Author:         David R. Butenhof
        Publisher:      Addison-Wesley
        ISBN:           0-201-63392-2

For your earlier question regarding the use of select() get:
        Title:          Unix Network Programming
        Author:         W. Richard Stevens
        Publisher:      Prentice Hall
        ISBN:           0-13-949876-1

or the later version
        Title:          Unix Network Programming Volume 1 (Second Edition)
        Author:         W. Richard Stevens
        Publisher:      Prentice Hall
        ISBN:           0-13-490012-X

IBM used to include adequate books in the Softcopy Library on both Socket
Applications and Multithreaded Applications.  They have been moved to the
so-called Information Centre as a series of separate web pages and have
been completely destroyed in the process.  I see the Sockets Programming
Guide is available as a PDF and so is still usable.  I could not find a PDF
version of the Multithreaded Applications book.

 1.0  Where to Find Information on Multithreaded Applications
   Use the AS/400 Information Center to find information on the following
   multithreaded applications topics:
      Managing Threads on AS/400
      Thread Safety
      Multithreaded Programming Techniques
      Language Access and Threads
      Debugging and Servicing of Multithreaded Jobs
      Performance Considerations in Multithreaded Applications

Simon Coulter.
