			AmigaDOS provides a process that you can use, called '''Command Line Interface''' or '''Shell'''. There may be several Shell processes running simultaneously, numbered from 1 onwards. The Shell processes read '''commands'''

			and then execute them. To make additional Shell processes, you use the NEWSHELL or RUN commands. To remove a Shell process use the ENDSHELL command. (You can find a full description of these commands in Chapter 2).
	AmigaDOS is built on Exec basis and extends parts of it. One important example of this enhancement is the concept of Process.
	As it's known, Exec gives you capabilities to handle processes called Tasks, however a Task doesn't have tools to handle I/O with memorize units. AmigaDOS gives you a new kind of extended Task which is called Process. An AmigaDOS process is a task with capabilities to handle files and so to interact with them.

	To handle Processes, AmigaDOS gives you many utility function to create and destroy them, and many other ones to handle files, directory etc... These utility functions are grouped into dos.library.

	A particular AmigaDOS process is the Filesystem: it handles how files and directories will be memorized on disks, and it receives all requests you will do with dos.library functions concerning files and directories. Filesystem will reply you using dos.library functions returns, so for you this communication is totally transparent.

	Interface''' or '''Shell'''. There may be several Shell processes running
	simultaneously, numbered from 1 onwards. The Shell processes read '''commands'''
	and then execute them. To make additional Shell processes, you use the
