Mathematica 387 and Mathlab 386 do not run properly in Microsoft Windowsversion 3.0 protected modes (standard and enhanced). These programs use theVCPI (virtual control program interface) to access extended memory thatconflicts with Windows in protected mode (standard and enhanced).
The VCPI specification allows MS-DOS applications to directly accessextended memory on 80386 machines. Windows uses the DPMI (DOS protectedmode interface) specification. The DPMI specification allows MS-DOSapplications to directly access memory on 80286 and 80386 machines. Manyprograms that use the VCPI specification, including Lotus 123 version 3.0,run correctly in standard mode Windows. The performance of an MS-DOSapplication that uses the VCPI specification depends on how closely theactual application follows the VCPI specification.
