B D is right, but the situation, which is documented unambiguously, is just a little more complicated:
<begin extract> The DCBE must not be shared by multiple DCBs that are open. After the DCB is successfully closed, the user may open a different DCB pointing to the same DCBE. Your program may refer to DCBE fields symbolically by using the IHADCBE mapping macro and the DCBDCBE address in the DCB (using the DCBD mapping macro). <end extract> DCBEs may not be shared among open DCBs. They may be reused, which is unsurprising. The DCB does contain a current pointer to its DCBE, and this may be the origin of the confusion.
