Section 13,7: Assignment

 Assigns the value of the expression to the variable.
 Arithmetic/Logical/Character assignment takes the form:

    v = e

    v  Is a scalar memory reference.
  
    e  Is an arithmetic expression (arithmetic assignment), 
       a character scalar memory reference (character assignment), 
       or a logical scalar memory reference (logical assignment).

 The right side of the equation must evaluate to a data type
 compatible with the variable on the left side.  If aggregates are
 involved, the aggregate reference and the aggregate must have
 matching structures.
