I'm a bit confused about how to get GETMAIN to give me an amount of
memory determined at execution time, rather than assembly time.  I seemed
to have no problems with

     GETMAIN R,LV=1000

What would I have to specify to get, say, a number of bytes equal to the
number of bytes in register 2?  GETMAIN always returns a chunk of memory
alligned on a doubleword boundary, right?

 Yes, you get doubleword alignment.
