On PRIME machines running the PRIMOS operating system, sharing
of library routines is accomplished via a strange call-by-name.
The name of the routine is provided to the OS, it looks up the address, and
MODIFIES the calling instruction to directly this address.  I
don't like this, but it works pretty well.
