Creating and
Managing a High-PIN
Process
This subsection describes how to convert a program that creates and manages a new
process. The converted program uses the D-series enhanced interface. The process
you create must already be converted to run at a high PIN as described under
“Converting a COBOL85 Program to Run at a High PIN” earlier in this section.
Figure 4-3 shows the processes involved in converting a typical application. The steps
described in this subsection apply to the requester process $REQ, which creates the
high-PIN server process $SRV.

This subsection covers the following topics:
Programmatically creating a new process at a high PIN
Managing a high-PIN process, including activating, suspending, stopping, and
abending the process, as well as invoking Inspect or Debug for the process
For information on how to interactively create a high-PIN process using TACL, refer to
