IIRC, DS  0H will fill 
with zeros just as will DC 0H.  Why is the latter  preferable? 


DS 'any operand'  will not fill the reserved space with  anything.  The 0H in 
this case functions only to align to a half word  boundary.
 
DC 'any operand' will fill with X'00' bytes any space that is  skipped over 
in order to provide the requested alignment, then generate the  requested 
constant.  But if the 'any operand' has a multiplier of 0, then  no filling 
code of 
X'00' bytes is generated.  In this case the 0H functions  the same as if the 
DC were a DS, namely you get aligned to a half word  boundary.
