For your information and possible amusement, I have a printed copy of SA22-7832-06 (February 2008) on my desk and it is 2.5 inches thick (6.5 cm)

One measure is "number of unique opcodes available". ... Another measure might be the thickness of a printed copy of PoO. My S/360 edition is about 3/8" - 1/2" . Does anyone have an actual printed copy of the current PoO? A page count from Acrobat would work, too. According to Acrobat: A22-6821-00 (no date - 1964?) has 168 pages. SA22-7832-07 (Feb 2009) has 1344 pages, exactly(!) eight times the original. At least this includes a (primitive) measure of the additional complexity, not just the instruction count.
