I saw the message of MEIRTE Danny about DP 32 bit. DP sources are targeted to produce a DOS program, calling DOS functions! Windows 64 bit simply doesn’t facilitate DOS programs, only Windows 32 or 64 bit programs.
DOS programs always start off as 16-bit. With MUCH programming effort, one could modify the source code and link in a DOS extender. Switching to 32 bit mode, when needed, and enable DP to access memory beyond the DOS 1MB limit. So frequently freeing up memory by swapping to disk isn’t needed anymore. It would surely speed up DP processing when it runs out of DOS memory. But DP would still be a 16 bit, with 32 bit extensions, DOS program, not able to run in Windows 64 bit! This is a dead end. If the source code would be available, the only practical approach would be to add XMS memory management to DP and let it swap to that.
