The STARTING WITH predicate tests whether or not the first
    characters of the first value expression match those specified
    in the second value expression. The STARTING WITH predicate has
    the following form:

  (B)0starting-with-predicate =                                   
                                                              
  qq> value-expr qwqqqqqqwq> STARTING WITH qq> value-expr qq> 
                  m NOT qj                                    
                                                              

    Because the STARTING WITH predicate is case sensitive, it
    searches for uppercase characters and does not include lowercase
    characters for the DEC Multinational Character Set; the reverse
    is also true. For example, STARTING WITH 'Ç' retrieves a set of
    records different from those retrieved by STARTING WITH 'ç'.

    The STARTING WITH predicate is sensitive to diacritical markings
    used in any Multinational Character Set. Therefore, a matches a,
    but neither matches á, à, ä, Á, À, Â and so on.

    In Spanish, ch and ll are treated as if they were unique
    single characters. For example, if a domain is defined with
    the collating sequence SPANISH, then STARTING WITH 'c' does not
    retrieve the word char, but retrieves the word cat.
