Section 8,10: Variables

 A variable is represented by a symbolic name which is associated
 with a storage location.  The value of the variable is the value
 currently stored in that location; the value can be changed by
 assigning a new value to the variable.

 Variables, like constants, are classified by data type.  When data
 of any type is assigned to a variable, it is converted, if
 necessary, to the data type of the variable.  You can establish the
 data type of a variable by type declaration statements, IMPLICIT
 statements, or predefined typing rules.
