- I just read in the last issue of Dr Dobbs Journal an article on the new
- BP7. The author stated that he was only able to get 4 megs of extended
- memory from his machine which had a total of 16 megs of ram. Is this true,
- and if so can someone explain why? Also- when a program is in protected
- mode, does it have to switch back to real mode to use msdos function calls
- like file i/o? In protected mode, is the extended memory only available
- for data/variables or can code exist there as well? In other words, does
- your code still have the 640K limit, or can you have a non-overlayed
- program with 2 megs of code? Thanks for your time..
