/GRANULARITY=keyword D=/GRANULARITY=QUADWORD

                                  OpenVMS Alpha and OpenVMS I64 only

 Directs the compiler to generate additional code to preserve the
 indicated  granularity.   Granularity  refers  to  the amount of
 storage that can be modified when updating a variable.

 You can specify the following values for keyword:

  o  BYTE

  o  LONGWORD

  o  QUADWORD (default)


 To update a variable that is smaller than a longword, HP  Pascal
 may   issue  multiple  instructions  to  fetch  the  surrounding
 longword or quadword, update the memory inside  to  longword  or
 quadword,  and  then  write  the  longword or quadword back into
 memory.   Using  /GRANULARITY  causes  the  compiler  to   avoid
 fetching  surrounding  memory  at  a  potential increase in code
 size.

 If multiple processes are writing into memory that is  contained
 in  the  same  longword  or quadword, you might incur inaccurate
 results unless /GRANULARITY=BYTE or some  other  synchronization
 mechanism is used.
