Assignment

 An assignment statement uses  an  assignment  operator  (:=)  to
 assign a value to a variable or function identifier.

 Syntax:

    variable-access := expression

 The 'variable-access' is an identifier, array component,  record
 component, pointer dereference, or file buffer.

 The  'expression'  is  a  run-time  expression  whose  type   is
 assignment  compatible with the type of the variable.  The value
 of the expression is the value assigned to the variable.
