Activating a Process (PH Capability Required)

If your program has PH capability, it can call the ACTIVATE intrinsic to activate a process that has been previously suspended (or just created) by the actions of these intrinsics:

The ACTIVATE intrinsic moves the specified child or parent process from a suspended state to an active state. . In addition, the ACTIVATE intrinsic optionally enables your program to suspend itself as soon as it activates the specified process.

Your program can only activate the parent process or a child process. Also, your program must have permission to activate the specified process (refer to the discussion of suspending a process). For example, only the parent process can activate a newly created child process.

This is an example of an ACTIVATE intrinsic call:

        .

        .

        .

   SUSP := 2;

   CREATE (BNAME,,PIN,,FLAGS);

   ACTIVATE (PIN,SUSP);

        .

        .

        .

The parameters specified in the example above are described below.
