Controlling System Activity

Process Handling (PH) 

This capability allows the direct creation of other processes by
executing the user process.  It also allows process suspension,
interprocess communication, and process deletion.

With process handling capability, a program can use any of the following
intrinsics:  ACTIVATE, CREATE, FATHER, GETORIGIN, GETPRIORITY, GETPROCID,
GETPROCINFO, KILL, MAIL, RECEIVEMAIL, SENDMAIL, SUSPEND, and TERMINATE.
For further information, refer to the MPE XL Intrinsics Reference Manual
