I've already seen another comparison table about performance (on dm site I think). But I found that with the METAKIT library, digitalmars executable is 3 times slower than VC5 !! search in 50000 records database with vc5 : 24.931111 ms/search search in 50000 records database with dm8.38: 65.156000 ms/search and this is a problem particularly because I use the metakit library for quick searches...

There is Open Watcom 1.0 and 1.1 (1.2 RC for braves). They internally have __WATCOMC__ predefined with value adjusted to mark continuation of development but using it for naming whole product is like calling DMC Symantec C++ just because it has __SC__ predefined. Any chance for such interesting article about strong FPU/double operations? ABX

I'm still stuck in the old Watcom mode. I should start talking about OW 1.0 etc. Please feel free to point it out if I do it again. :)Which version of the compiler was it?BTW, Matthew, afaik there is nothing like Watcom 12.0 listed in your article.

There is a strong chance, once I'm past the book deadline (2nd Feb). By all means write to me again after that time and remind me Cheers Matthew
