Shared system routines

[guy at rlgvax.UUCP]

Just out of curiosity, how did the EXEC 8 system handle global references
from the shared library to data, rather than routines, outside of it?  Did
it use the Multics technique of using an indirect pointer to refer to any
external, whether code or data; did it just forbid such references; or did
it find a third way out?
