Hello Frans,

311     Operand of HIGH operator was larger than H'FFFF'.
        The HIGH operator will return the value of the bits 8 through
        15 of the operator, shifted down to the lower byte.  Any bits
        above bit 15 are ignored.  The expression HIGH (H'123456')
        evaluates to H'34'.

Quoted from page 116 of DS33014F.
