- Could someone please drop me a quick note and tell me what the deal is
- with "32-bit" programming on 80n86 machines?
-
- My understanding is that all of these cpus have segment based adressing
- as far as the instruction set goes. Thus you get problems such as
- a 64K limit on mem allocs in many programming language compiler
- implementations.
-
- But now I hear about OS/2 ver 2, windows NT and some compilers that do
- 32-bit programming. What does this mean?
-
- And I hear of pascal compilers that allow you to allocate contiguos
- chunks of memory that are arbitrary in size.
-
- thanks
