For example the command MEMEX 10000 12000 mfb 10000 12000 12 will cause the following: 1) The messages and memory contents are printed out 2) The system pauses for 2 seconds, allowing time to observe the output, or to type for more time. 3) The command mfb 10000 12000 12 is executed. 4) The memory range is printed out again.
