  Argument
 
    ordinal_value    Ordinal expression
 
  Returns
 
    LongInt          Ordinality of ordinal_value in set of scalar
                     values
 
  Description
 
    The Ord function returns a LongInt containing the ordinality of
    ordinal_value within the range of scalar values for the ordinal
    type of ordinal_value.
 
    The numbering of an enumerated type begins at zero for the first
    element. For the last element, Ord returns a value one less than
    the number of elements. For example, if an enumerated type MyType
    has three elements, Ord returns a value of 2 from the call
 
       result := Ord( Last( MyType ) );
 
    Ord returns an ASCII code when passed a character. The Chr function
    operates as the inverse of Ord, returning the character represented
    by a given ASCII value. For example, to return the ASCII value of
    the letter 'A':
 
       result := Ord( 'A' );
 
    The ordinality of a value of integer type is equal to that value.
