You find AmigaDOS commands in two places. The primary location is the C: directory, which, unless you changed it, is assigned to the Sys:C directory. On the Amiga 3000 release disk, this directory holds 43 AmigaDOS commands; the number probably won't vary in the releases for the Amiga 500 and 2000. You can view these commands by entering: DIRC:
Figure 8-1 shows the output of this command. In addition, with Amiga OS 2.0, 30 AmigaDOS commands are stored in the system's Kickstart ROM and are thus always available. You can see these com mands by entering: RESIDENT
The commands marked Internal (see Figure 8-2) are those contained in Kickstart. Notice that three commands found in the C: directory — Assign, List, and Execute — also show up in the list of resident commands, although they are not labeled as being internal. These are actually disk-based commands that are made resident by the Workbench2.0 and System 2.0 Startup-se quence. You'll learn more about the Resident command later in this chapter. For purposes of organization, I've divided the 73 AmigaDOS commands into three categories and devoted one chapter to each category. This chapter deals with commands that give you information about the current state of AmigaDOS and, in many cases, let you change that state. (I call these the in formation and configuration commands.) Chapter 9 deals with commands that let you modify files and devices, while Chapter 10 describes how you cre ate and modify command scripts.
