For one very large Hartford, CT, insurance company, there were 11,024 executables in production libraries on 2012 January 3, of which 7,403, or 67.2% were AMODE(24).
This number is unweighted for usage, which may well be zero for some of them, and I have the impression and some evidence that frequently and heavily used executables are more likely to be AMODE(31). Only 23 of the 100+ production programs that are executed on every weekday are, for example, AMODE(24). In making this calculation I have classified mixed-mode programs that themselves make some explicit use of AMODE(31) as AMODE(31). However such numbers are looked at, it is my impression that there is still much more AMODE(24) execution going on than seems at all 'reasonable'. (I have not myself written even a snippet of such code in many years.) John Gilmore, Ashland, MA 01721 - USA
