The ENVIRON [[associative container]] contains the values of the current environment. This enables an environment variable to be accessed by using the environment variable name as [[key]] within the container: {{{ BEGIN { print "Your home directory is "ENVIRON["HOME"] } }}} == Manipulating the container does not export the revisions to a subprocess == Note that the ENVIRON [[associative container]] can be changed by [[assignment]]. However, this does not affect the environment passed on to [[subprocess]]es that may be spawned from [[awk]], either via the [[system]] command or through [[redirection]].
Summary:
This change is a minor edit.
