RE: threading in rpg. was RPG and Web.. (was Using OO conceptsinRPG)

[Tom Daly <Tdaly@xxxxxxxxxxxxxx>]

I understand the _concept_ of threading within a job, not necessarily all
the ins and outs.  I'd have to re-read some books.  When writing server
programs, such as for sockets, almost all examples are in C (Scott K's
excellent primer the exception).  Some of these C pgms use & illustrate
multi-threaded techniques.  Not having C as an option here, I'm curious if
there are ways to implement threads using RPG.


 |  Unfortunately for us, the word 'thread' has been in common 
 |  use in the AS/400
 |  arena for a while.  In this context, it means 'job', as in 
 |  'multi-threaded
 |  job queue' allows multiple jobs to process simultaneously.  
 |  The discussion
 |  at hand is about Unix threads, which are parallel processes 
 |  running in the
 |  same job.  Imagine having an application that loads up a 
 |  dozen arrays, sorts
 |  them and then prints them out.  You could conceptually 
 |  spawn 12 threads from
 |  your program where each thread loads an array and sorts it. 
 |   As each thread
 |  completes, it has to notify the main thread that it is 
 |  complete.  Then the
 |  main thread prints the arrays.  All in one program, all 
 |  parallel tasks.
