variable
var

    (Sometimes "var" /veir/ or /var/) A named memory
   location in which a program can store intermediate results and
   from which it can read it them.  Each programming language
   has different rules about how variables can be named, typed,
   and used.  Typically, a value is "assigned" to a variable in
   an assignment statement.  The value is obtained by
   evaluating an expression and then stored in the variable.  For
   example, the assignment

   	x = y + 1

   means "add one to y and store the result in x".  This may look
   like a mathematical equation but the mathematical equality is
   only true in the program until the value of x or y changes.
   Furthermore, statements like

   	x = x + 1

   are common.  This means "add one to x", which only makes sense
   as a state changing operation, not as a mathematical equality.

   The simplest form of variable corresponds to a single-word
   of memory or a CPU register and an assignment to a
   load or store machine code operation.

   A variable is usually defined to have a type, which never
   changes, and which defines the set of values the variable can
   hold.  A type may specify a single ("atomic") value or a
   collection ("aggregate") of values of the same or different
   types.  A common aggregate type is the array - a set of
   values, one of which can be selected by supplying a numerical
   index.

   Languages may be untyped, weakly typed, strongly typed,
   or some combination.  Object-oriented programming languages
   extend this to object types or classes.

   A variable's scope is the region of the program source
   within which it represents a certain thing.  Scoping rules are
   also highly language dependent but most serious languages
   support both local variables and global variables.
   Subroutine and function formal arguments are special
   variables which are set automatically by the language runtime
   on entry to the subroutine.

   In a functional programming language, a variable's value
   never changes and change of state is handled as recursion over
   lists of values.
