in reference to my prior posting on this topic, it should be remembered that a multiply by 72 is a cheap operation ((n<<3)+(n<<6)) which is likely the reason that 72 was picked for points. Since the language gives you a way around this, (simply change the scaling matrix), it is not one of my sore points with Adobe. They picked a reasonable approximation, and then gave you the ability to override it. Unfortunaly developers of applications were not familiar with 72.3 in general, and so did not bother to change the scaling matrix in thier software like they should. For most cases it really does not matter, but in the case where you are working with printers (people) and other typesetters it is important. Cheers Woody
