  4. 4. WINDOW ENVIRONMENT DEFINITION Refers to computers running under a Microsoft Windows operating system. Also called a "windowing environment," it refers to any software that provides multiple windows on screen such as Windows, Mac, Motif and X Window. Also may refer to an application that provides multiple windows for documents or pictures.
  5. 5. WORKING IN THE WINDOW ENVIRONMENT ENVIRONMENT:an area of memory associated with the command processor that provides up to 32KB of space for storing variables,contain information about the operating environment that is used by the operating system and other programs in various ways.
  6. 6. EXAMPLES OF THE WINDOW ENVIRONMENT ComSpec: specifies the location of the command interpreter. PATH :specifies the locations to search for commands typed at the command line. Prompt :specifies how the command prompt should appear to the user. AGE :a user-defined variable for indicating the age of something. TEMP :specifies the directories where temporary files should be placed.
  7. 7. SETTING UP ENVIRONMENT VARIABLES1. From the start menu go to settings then control panel2. Double click on the System icon, this will bring up a dialog box.3. Click on the advanced tag and then environment variables, this will bring up another dialog box with two scrollable windows, in Windows 2000 the top one is for local variables and the bottom for SYSTEM variables, in Windows NT it is the other way round.4. Find the environment variable named PATH and click on it. It should be self-explanatory. To edit a variable, click on edit, to add a new variable, click on new. The only SYSTEM variable we will edit is PATH all the other environment variables we will edit will be LOCAL. When I talk about appending to/adding to an environment variable I mean editing it and sticking another file name on the end.5. Windows uses the convention that environment variables are separated by this character ";" If you are appending to a list of directories make sure you add this character onto the end of the list before you add your directory to the list. Do not add ";" after the last file name in the list as this may cause problems, just make sure that directory entries are separated by ";"s.
