So I guess you are saying Nick that the folks who designed Fortran 95 did not know what they were doing, and that the parallel loop is a silly unnecessary construct :-) I really think you should read through the old thread on for all if it can still be found somewhere. There are a lot of subtleties here that have occupied the minds and research programs of a lot of top people in the compiler field, and you really should read the literature in this area before making pronouncements like the one above! -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
