+You can think of a variable as a place in the computer's memory to store things.  Each variable has a name that must begin with a letter, and may consist of any number of letters, numbers, and dollar signs.  Their names are case sensitive, the variable 'a' is not the same as the variable "A".\\
+In BASIC-256 you do not need to define a variable before you use it.  The variable is created when it is assigned a value for the first time and will retain its value until the program [[end|end]]s or the variable is [[unassign|unassign]]ed.

-In previous versions (before 1.99.99.8) Variables that contained strings were required to end with a dollar sign ($).  This limitation has been removed and any variable may store any type of value.\\
