But it's useful.
It there aren't enough blanks to compress out, will the line be extended, possibly reallocating a buffer if necessary?

But I suppose the Reference will happen soon enough. So for BPXWDYN the programmer will have his choice of PARMDD or STDPARM. I wonder if it makes any difference?
