Section 8,4: Constants

 A constant is a fixed value.  The value of a constant can be a
 numeric value, a logical value, or a character string.  There are
 seven types of constants:  integer, real, complex, bit, logical,
 character, and Hollerith.  Bit and Hollerith constants have no data
 type; they assume a data type that conforms to the context in which
 they are used.
