Given an invocation context block and a quadword IP value in ip_copy, write the ip_copy value to the invocation context block IP and then use LIB$X86_PUT_INVO_REGISTERS to write to the actual context. The invocation context block remains unchanged if the routine fails. LIB$X86_SET_IP fails if LIB$X86_PUT_INVO_REGISTERS fails. Format LIB$X86_SET_IP (invo_context, ip_copy)Additional Information: explode extract
