	Environment Variables in Windows XP
		Environment Variables in Windows XP Environment variables are specially named aliases or placeholders for certain basic system properties that are present for convenience in programming and in system administration.
		Environment variables have long been used in computer operating systems and are present in Unix, DOS, and Windows The word "environment" used in the context here refers to various features of the computer system and certain basic system data.
		Environment variables are very convenient in scripts where certain standard directories and parameters need to be referenced but where the actual locations or names can vary from computer to computer.

	Environment Variables
		Environment variables that apply to a single utility only are defined as part of the utility description.
		The values that the environment variables may be assigned are not restricted except that they are considered to end with a null byte and the total space used to store the environment and the arguments to the process is limited to {ARG_MAX} bytes.
		This environment variable determines the interpretation of sequences of bytes of text data as characters (for example, single as opposed to multi-byte characters), the classification of characters (for example, alpha, digit, graph), and the behavior of character classes.

	environment variable - a Whatis.com definition (Site not responding. Last check: 2007-10-13)
		Environment variables are used across multiple languages and operating systems to provide information to applications that may be specific to the user request.
		For example, "TERM" (environment variables are expressed as upper case by programming convention) defines the type of terminal used, "PATH" defines the directories to be searched for programs corresponding to command names, and "USER" defines the particular user, so that access permissions may be checked for each request.
		Other environment variables are specific to the type of request being sent, such as "SERVER_PROTOCOL," which identifies the name and revision of the protocol used for the request, and "REQUEST_METHOD," which identifies the method used for the request.

	Environment variable - Wikipedia, the free encyclopedia
		Environment variables are a set of dynamic values that can affect the way running processes will behave on a computer.
		Shell scripts and batch files use environment variables to store temporary values for reference later in the script, and also to communicate data and preferences to child processes.
		In Unix, the environment variables are normally initialized during system startup by the system init scripts, and thence inherited by all other processes in the system.

	Environment - Wikipedia, the free encyclopedia
		In biology, ecology, and environmental science, an environment is the complex of physical, chemical, and biotic factors that surround and act upon an organism or ecosystem.
		The environment may or may not be able to interact with the system, depending on whether it is a open or closed system.
		In computing, an environment is the overall system, software, or interface in which a program runs, such as a runtime environment or environment variable, or through which a user operates the system, such as an integrated development environment in which the user develops software or a desktop environment.

	Environment Variables in Apache
		Although these variables are referred to as environment variables, they are not the same as the environment variables controlled by the underlying operating system.
		For additional flexibility, the directives provided by mod_setenvif allow environment variables to be set on a per-request basis, conditional on characteristics of particular requests.
		In addition to all environment variables set within the Apache configuration and passed from the shell, CGI scripts and SSI pages are provided with a set of environment variables containing meta-information about the request as required by the CGI specification.

		However note that for the directory and path separators, when the variable is put into the environment, the use of these separators may not be recognized on the differing platforms.
		The environment variable MAYA_LOCATION must be set, and must be set to something valid, or Maya may have difficulty running.
		If this environment variable is set, then don't load the file (initialLayout.mel) that creates the UI.

	EnvironmentVariableTarget Enumeration (System)
		The environment variable is stored or retrieved from the environment block associated with the current process.
		However, the environment variable in the registry persists until the user removes it programmatically or by means of an operating system tool.
		The target can be one of three locations: the environment block associated with the current process, the Windows operating system registry key reserved for environment variables associated with the current user, or the registry key reserved for environment variables associated with all users on the local machine.

	Set - Environment Variable
		Environment variables allow you to store values (numbers or text) for later use, variable names are not case sensitive but the contents can be.
		The /P switch allows you to set a variable equal to a line of input entered by the user.
		Variables set in this way are not available to 32 bit gui programs - they won't appear in the control panel.

	How to Use Environment Variable Substitution in Batch Files
		This procedure is known as environment variable substitution.
		%PATH% is an environment variable whose value is taken from the current environment and appended to the new PATH definition.
		If the variable specified by the SET command is not defined in the environment, the variable stays the same if used at the prompt, and is replaced by a null expression if used in a batch file.

	CGI Environment Variables
		These environment variables are set when the server executes the gateway program.
		In addition to these, the header lines received from the client, if any, are placed into the environment with the prefix HTTP_ followed by the header name.
		Examples of the setting of environment variables are really much better demonstrated than explained.

	The CYGWIN environment variable
		environment variable is used to configure many global settings for the Cygwin runtime system.
		Note that this is may cause problems if the mount table changes, as the cache is not invalidated and may contain values that depend on the previous mount table contents.
		However, this shouldn't be a problem in NT domain environments.

	update the path environment variable at runtime - MSDN Forums
		You can use registery to create the environment then your OS will recignize the path.
		My suspicion is that this will only impact the environment of the process that is running (your program).
		There is no impact on the environment at the command level.
