Just to let everybody updated , Dataperfect is running fine on Windows
10/ 32 bits ( uhuhhuh +10 years of DP!)

I've commented on this topic in the past as I too wish for a 32-bit
version of DataPerfect.
I believe DataPerfect is written in Forth and know numerous 32-bit
Forth compilers and/or interpreters exist including a /Win32 Forth./ See:
https://en.wikipedia.org/wiki/Forth_%28programming_language%29
<https://en.wikipedia.org/wiki/Forth_%28programming_language%29>
A Windows version of DataPerfect would be great but I'd be happy with
a 32-bit version that would run natively in current 64-bit versions of
Windows; operating in a DOS window would be a minor issue compared to
setting up virtual machines.
I may have missed it but I've never seen Lew comment on this direction
and would love to know his feasibility assessment of this direction.
Thanks,

Sorry to hear that you consider a compiler 'swap' a dead end.
I hoped to solve the 64-bit problem as I did with all the helper
programs I wrote in QuickBasic (yes the compiler written by Bill
Gates himself).
Using QB64 I could compile everything in 32-bit so they should work
also in the 64-bit environment. With some minor changes in the source
code e.g. replace "END" by "SYSTEM".
I suppose that the programs generated just run in a DOS-window, but
do not start as 16bit DOS programs.
They need separate DLL files (to be stored in the same directory or
in a common windows directory) see
http://www.qb64.net/wiki/index.php/QB64_FAQ#Q:_What_files_are_required_to_run_QB64_SDL_programs_in_Windows.3F
Probably this is the only way to reuse the former source code, where
some DOS functions are transferred to the DLL's...
Might be a hint for those who want to save DP...
Maybe someone can find a way to 'adapt' the source code of DP for a
32-bit compiler.
But as long as the code of DP is not open source, this is really a
dead end...
Lew was once thinking about a Win-version of DP, 'DPWin'...

Subject: [Dataperf] Dataperfect and Windows 64bit Win7
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.
