Environment \En*vi"ron*ment\, n. [Cf. F. environnement.]
     1. Act of environing; state of being environed.
  
     2. That which environs or surrounds; surrounding conditions,
        influences, or forces, by which living forms are
        influenced and modified in their growth and development.
  
              It is no friendly environment, this of thine.
                                                    --Carlyle.

  environment
       n 1: the totality of surrounding conditions; "he longed for the
            comfortable environment of his livingroom"
       2: the area in which something exists or lives; "the
          country--the flat agricultural surround" [syn: environs,
           surroundings, surround]

  environment variable
       
           A variable that is bound in
          the current environment.  When evaluating an expression in
          some environment, the evaluation of a variable consists of
          looking up its name in the environment and substituting its
          value.
       
          Most programming languages have some concept of an environment
          but in Unix shell scripts it has a specific meaning
          slightly different from other contexts.  In shell scripts,
          environment variables are one kind of shell variable.  They
          differ from local variables and command line arguments in
          that they are inheritted by a child process.  Examples are
          the PATH variable that tells the shell the file system
          paths to search to find command executables and the TZ
          variable which contains the local time zone.  The variable
          called "SHELL" specifies the type of shell being used.
       
          These variables are used by commands or shell scripts to
          discover things about the environment they are operating in.
          Environment variables can be changed or created by the user
          or a program.
       
          To see a list of environment variables type "setenv" at the
          csh or tcsh prompt or "set" at the sh, bash, jsh
          or ksh prompt.
       
          In other programming languages, e.g. functional programming
          languages, the environment is extended with new bindings when
          a function's parameters are bound to its actual
          arguments or when new variables are declared.  In a
          block-structured procedural language, the environment
          usually consists of a linked list of activation records.
