You are right.  I did simplify the system service dispatching as it involves moving arguments between stacks, various PROBEs, etc.  I'm not going to describe the whole mess (partially because I've never looked at the whole mess)

SYS$QIO is in the [SYS] facility, SYSTEM_SERVICES.LIS.  You will not find any code in STARLET.OLB for a system service.

             03B0       SYS$QIO::
             03B0       QIO:
A77B0010     03B0               LDQ     R27, 16(R27)   ; 015214
A79B0008     03B4               LDQ     R28, 8(R27)
6B9C4001     03B8               JSR     R28, R28
