Chapter 14: THE NOS COMMAND SET SUMMARY

 

NOS has over 80 separate commands, and getting your mind around them is not a 5-minute job! Also, most of the commands have several options, complicating matters even further. This chapter puts the commands into logical groups, and provides a brief description of each one. In later chapters we will look at most of them again in much more detail. (See Appendix 2 for full command syntax information).
