I am running a DOS application on my laptop and I get a run time error indicating OUT OF ENVIRONMENT SPACE. I have seen this before with WIN 95 and corrected it by right clicking on the DOS window and allocating more memory to the initial environment setting. Is there a similar way of doing this in Windows 2000? thanks.

Hi there.

If I understand what your asking properly then no. All 16bit apps run as separate threads in a single multithreaded NTVDM.exe.

As a result running multiple 16bit apps can cause problems. Since they are in the same application memory space (NTVDM). Using the command line 'start /separate {processname}' you can cause a new 16bit app to run in it's own address space. (It also allows better monitoring of multiple legacy apps (instead of trying to map threads to processes within NTVDM)

All applications are allocated 2GB address space for runtime.

Ensure your RAM pagefile isn't badly fragmented or too small, or it's not on a partition getting full (above 90-5%).

Perhaps your initial runtime is setting some bad env settings also.

Ensure your permissions are not causing the conflict, and check to make sure they are the right type of environment variables. Your DOS program assumes administrator rights so if your app isn't getting admin level rights your DOS program may not know how to handle the error.

Perhaps your vendor could also provide some insight for the DOS tool.

I realize this may not help or answer the question properly, sorry I couldn't be more help.

then again, perhaps it's because in an emu-dos cmd.exe window on windows 2000 you only have 1mb of ram.

Try setting a msdos shortcut to it.

Then in the shortcut settings, in memory
set the initial environment mem to 1024.

:o)
Have a nice day......

Go the winnt directory. Right mouse click on the file _default then click on create shortcut and move it to your desktop.
You can then right click and go to properties and have all the settings you used to have including environment space. Just set up your command line and working space.

If the program runs a batch file that contains environment variables, right click my computer and go to properties, click the advanced tab and click environment variables, then under user variables, add a name and path for each one.

Works like a charm
