Byte Alignment question with Change User Space Attributes API (QUSCUSAT)

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

In the docs for the  Change User Space Attributes API (QUSCUSAT) is the 
following:

"Each variable length record must be 4-byte aligned. If not, unpredictable 
results may occur."

also this:

"If you specify a length of data that is longer than the key field's defined 
data length, the data will be truncated at the right. No error message will be 
returned."

Now for example, the Initial value key has a data field that is only 1 byte 
long.  Does this mean that you should add 3 bytes of filler so that the next 
key is on a 4 byte boundary?

example ds

     d t_InitialValueAttr...
     d                 ds                  qualified
     d  key                          10I 0 inz(2)
     d  dataLength                   10I 0 inz(%sizeof(data))
     d  data
     d   initialValue                 1a   overlay( data : *NEXT )
     d                                3a   overlay( data : *NEXT )
