Seems to me, I've seen more than 1 page counter declared as binary. Because every one knows binary arithmetic is more efficient. :) I think with today's processors, that load, add, store sequence runs pretty fast. Maybe as fast as one instruction. Not to say that your point isn't valid. When we got one of the later Z machines, our Strobe performance monitor became mostly useless. It would show CPU being consumed in code that couldn't possibly be using significant CPU. IBM came in and explained with instruction look ahead and simultaneous execution it was no longer possible to isolate CPU use to instructions or even blocks of code. -- Dan Espen
