- symbolic ID of the target MI object

IMHO, under a couple of prerequisites, you can "reconstruct" a valid SPP by the following steps:
- resolving the system pointer (SYP) to the target MI object via the "symbolic object-ID" by using the RSLVSP instruction
- obtaining the SPP to the associated space of the target MI object using the SETSPPFP instruction upon the SYP
- set the offset into the space object via the "offset into space"
The prerequisites are:
- The target MI object can be resolved by the symbolic object-ID. For example, a space object whose addressability is not inserted into a context can not be resolved by the RSLVSP instruction.
- You can issue the SETSPPFP instruction on the resolved SYP successfully. For example, issuing SETSPPFP in a user state thread upon a system domain object will raise the Domain Violation (hex 4401) exception.
