The emulation method uses a number of data processors having different instruction word sets. An instruction which interrupts the operating system on the first data processor is defined. When the instruction is detected in a program runnig on the first data processor. It is determined whether or not the instruction is an instrcution associated with an input/output macro instruction. If it is found, as a result of the determination, that this is the case, an interrupt is caused in a program running on the second data processor which controls the emulation.
