Oh yeah, assembly - no sweat, you could do that on an old IBM360 along with floating point math and hosts of really awesome and incredibly mind numbing complicated stuff.
But non-relocateable machine code? You know, the stuff that's *really* doing the work? I've never seen any that could do a NOT and an = at the same time even on the 360. And with reduced instruction sets being all the rage, it's probably not been added, eh? In any event, it's not a significant enough to have any measurable effect on speed, but is easier to look at. Btw, the rumor was that the teacher that I had for year two of the 360 assembly, who used to write I/O routines in machine code for IBM at the time as his day job, lost his mind and sat in the corner laughing to himself before they finally gave him a padded suit. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Dan McGrath Sent: Wednesday, March 02, 2011 8:00 PM To: U2 Users List Subject: Re: [U2] Is this worth rewriting? #1 In x86 assembly, you use can use JE or JNE. So you do the comparison, then jump. How you jump (or don't jump) determines if it was an = or #. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Allen E.

There is NOT and = which is two comparisons. Now, granted, there have been significant improvements in cpu's since I did machine code in 1975, so maybe that has changed... <snip> _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
