Win xp64

I have just performed a test on an AMD64 running win XP 64, none of the dos
programmes so far tested will not work, this includes clipper 5.2 and 5.3 as
well as clipper compiled exes and blinker.  Reading around it looks as
though xp64 does not support dos systems at all.  Anybody else had this
experience?

Mike.

You said ..."none of the dos programmes so far tested will not work".
Double negative. Do you realise that means they all work? Is that what
you meant to say? I guess not.

So long ... and thanks for all the fish.

Well Mike,

WINXP 64Bit Version does not support any kind of 16Bit stuff

- no win3.1x stuff
- no 16Bit DLLs
- no pure DOS Programs

It supports all kind of 32Bit GUI and CONSOLE Windows programs.

That means:

Move your Clipper code to xHarbour as 32 or 64 Bit and be happy
for the next 10 years or more.

Special thanx to Ron, Patrick and the whole xHarbour and Harbour Team
for this great Compiler and Builder !!!

AMD64 in 64 bit mode does not support VM86 mode. AFAIK there is no
processor which can work in 64bit mode and emulate VM86 so far so you
will have forgot about any 16bit application in native CPU mode.
In Linux you can use DOSEMU compiled with BOCHS (CPU emulator) to
run 16bit application. Probably we will soon sth similar for Win64.
But remember that such emulation cause heavy overhead so I strongly
suggest to recompile your source code with [x]Harbour as native
32 or 64 bit Windows application.

Mike,

There is an open source product named "DosBox" (search on google) that
emulates a MsDos on 32 bits and runs ok on Windows x64.

I have used it to run Clipper applications on Windows x64 and they work
really fine.

Antonio

Yes, DosBox is nice. BTW, here is short interview with the authors:
