The best way I know of to do this sort of thing (in IDL) is to use
array-insertion starting offsets.
e.g., If you have 2-dimensional arrays and you want to copy one on top
of another, do:  TEMP1(0,0)=TEMP2.
This is much, *much* more efficient than using '*'.   It also converts
what it copies to the datatype of TEMP1 if necessary.
This issue goes back a long way, so I'd expect the "solution" to work
on PV-Wave as well.
