Variables revisited Article Index Variables revisited Global and
local scope Block structure    When you first start programming
a variable is something that you store data in until you need it
again.  Later on a variable becomes something much more
complicated with static, dynamic, local and global modifiers
that can be used as part of the declaration.  Thinking about how
variables can be implemented leads on to a more general topic of
names and how they are bound to the things that they represent.
This is an important topic that is central to object oriented
programming.  The variable makes us different  The basic idea of
a variable is one of the great ideas of computing and what
distinguishes it from mathematics.  In computing a variable is a
name bound to an area of storage. The principle method of
manipulating a variable is the assignment statement. For
example, in many languages you would write an assignment as
and it immediately becomes clear why variables and assignment
statements are not like mathe
