The first line in listing 7.1 represents a processing instruction. Processing instructions are used to feed special instructions to the parser. In this example (and most XML documents), the processing instruction tells the parser that the document that is being loaded complies with version 1.0 of the XML specification, which is governed by the World Wide Web Consortium (W3C). (See www.w3c.org for more information.) You will also use processing instructions to link Extensive Stylesheet Language (XSL) files to your document. The encoding section tells the parser the character scheme of the XML document that is being loaded. Lines 2 4 indicate an XML comment. This syntax is exactly the same as in HTML. One thing to note about comments is that they can t be embedded inside the tag names that describe the data in your XML document. Therefore, this is incorrect:

[void] $shell.Run("calc")

This returns the following result:

Technically speaking, the help system has no idea what commands are present in the shell. All it knows is what help topics are available. Fortunately, Microsoft ships a help topic for nearly every cmdlet that they produce, so there s usually no difference. In addition, the help system can also access information that isn t related to a specific cmdlet, including background concepts and other general information. Like most commands, Get-Help (and therefore Help) has several parameters. One of those perhaps the most important one is -Name. It s a positional parameter, so you don t have to type -Name and can simply provide the name you re looking for. This parameter specifies the name of the help topic you d like to access, and it accepts wildcards. This ability to handle wildcards is what makes the help system useful for discovering commands. For example, suppose I want to do something with an event log. I don t know what commands might be available, so I want to search and see what help topics talk about event logs. I might run either of these two commands:

gMyVar;

If you don t understand all the code right now, don t worry about it. We ll go through this program in excruciating, line-by-line detail soon. Source code is no fun if you can t turn it into a running program. Build and run the program by clicking the Build and Go button or pressing R. If there aren t any nasty syntax errors, Xcode compiles and links your program and then runs it. Open the Xcode console window
