Pentium > optimization is something really necessary nowadays, isn't it? Um, well, kind of. You're kind of running down the middle of a 2 way street. On the one hand, optimizing important Pent code in an important segment is a great way to go, since it also happens to optimize 486 (no ideas regarding pent pro--sorry), not to mention loads of fun. On the other hand, indiscriminitely compiling w/ "Optimizing For Asm" (or whatever it's called) enabled has a tendency to make the object code larger. Now, admittedly, code size is a lot less significant under p-mode than real. But the pent (?) only (?) has an 8M internal cache. Keeping inner loops under that limit should significantly increase performance. And help executable size. Etc, etc...basically all the reasons for optimizing in the first place. jimerthy Am I leaving myself wide open tonight, or what? > > TIA, > > Martynas
