10.6 Global variables

Global variables are accessible anywhere in a program. The term is also sometimes used sloppily to refer to variables with a broader scope than local variables - such as module variables that are accessible anywhere within a single file. But accessibility anywhere within a single file does not by itself mean that a variable is global.
