Note that GECO is an undocumented instruction. The NORD-1 instruction IOT (not listed) is also partly supported by SINTRAN-III through emulation (although the NORD-10 could be ordered with an actual IOT instruction option, for NORD-1 compatibility): IOT SKA (opcode 161000) is the equivalent of MONitor calls for the range 0-127 (MON 0 .. MON 177).
