Something just occurred to me. Exactly *where* are you trying to run this program? On a kn10-kl (the extended KL-10 CPU defined by klh10), on a SimH KS-10, or on a real CPU (KL, KS, or Toad)? I just had a look at the klh10 sources and find that Ken Harrenstien added the CIRC instruction to his KL emulation as well as his KS emulation in 2002. If you're running any klh10-based emulation, that instruction ought to work. It would only work on MIT-specific real hardware.
