Yes, for non-native speakers of any language, it would be nice to know how big the '''thingys''' are: ''int, short, long, long long'', etc. For experienced programmers, I imagine this is old hat, but to programmers who can barely spell '''C''', ... not so obvious. --- [[User:Gerard Schildberger|Gerard Schildberger]] 21:35, 30 May 2012 (UTC) |

The moving of 80386 to x86 Assembly
I think it is better to use generic x86, and at most to specify a "works with", if needed, rather than let proliferate 80286, 80386, 80486, ... —ShinTakezou 14:56, 27 April 2010 (UTC)
- I agree to a point; there's a definite progression and tendency toward backwards-compatibility. However, there are incompatible revisions. It's possible that different modes (real, protected, long and legacy) warrant some degree of recognition as their own languages--these modes represent forward and reverse compatibility constraints. --Michael Mol 16:03, 27 April 2010 (UTC)
