The following is the other half of placewindow (for those who remember
that). It will print out the location/size of any (or all) windows on
the system, upon request. Use is to place a window the way you want it
to be, and then dumpwindow it to get the nubers to plug into whatever
startup mechanism it has for placement - or placewindow if it has no
such mechanism. Output is suitable for handing to con: or placewindow
or etc. with editing.

One thing - I'm not sure about printf()'ing while IntuitionBase is
Locked. Don't think it should be a problem, and it hasn' yet. But
doing window manipulations while dumpwindow is working could cause
troubles. Then again, you should run dumpwindow unless everything is
stable anyway.


Compile with Lattice 5.01. Use short ints, and line with cres.o. All
works fine.
