GetEnv <variable> <environment variable name>
Gets the value of an existing environment variable. Unlike the standard notation with enclosing % signs, it allows you to get the value of any variables, including those whose names contain various special characters (brackets, percent signs, spaces, etc.)
|variable||The name of the variable to which the result of the command will be written.|
|environment variable name||Name of environment variable being read.|
The function also allows you to check if an environment variable exists. If the variable does not exist, the variable %ERROR% will be equal to 1.
