Hello,


I have applications developed in CLIPPER and they were developed in DOS.

In Windows98 there were commands to charge the OS in high memory to run DOS
programs.
Commands like:
DEVICE=C:\DOS\HIMEM.SYS /TESTMEM:OFF
DEVICE=C:\DOS\EMM386.EXE AUTO RAM
DOS=HIGH
DEVICEHIGH /L:1,15872 =C:\DOS\DISPLAY.SYS CON=(EGA,,1)


But in Windows XP how that works?...
Now, i'm having problems running such applications...

Any ideias will be appreciated.


Thanks,

Nuno Gomes

What problems do you experience? Please quote specific error messages!

One way to get around such issues is to run the application on a "Virtual
PC" - see here: http://www.microsoft.com/windows/virtualpc/default.mspx.
However, depending on the nature of your problem, there might be simpler
solutions.
 
I have aplications developed in CLIPPER with databases in DBASE.
It appear the message: "Cannot create VM swap file" and the application
stops.


Thank you for your help.

I have find the solution:
Edit config.nt and autoexec.nt. This files have the configuration to run DOS
programs.


But let me ask one more thing:
The DOS only read/write in a disk with a max capacity of 2Mb.
Using the Windows XP to run DOS programs in a disk with 40Gb what happens?
When the data in the disk go over 2 Mb the CLIPPER program works without
problem?...



Thank you for your help.

The problem is that i can't find a group to post questions about Windows
XP...
What is the correct group?..


Thank you,

2 MB is ONLY if the DOS is working with a FAT12 file system. But then XP
isn't DOS, or using DOS or using a FAT12 filing system.

No, the problem is that you posted the same question in several separate
threads instead of creating a proper cross-post as explained in the link
that John gave you. Now that I know that there are other threads on the same
subject I'm reluctant to contribute any further since other people might
have given you appropriate answers in the other newsgroups.
