I bought a new PC recently.

I was trying to put a cobol program onto this PC.

My PC is running Windows 2000 Professional Service Pack 3.

I know this cobol program works, I have used it on another PC before.

When I run the command,

C:\Rmcobol\Runcobol.exe /regserver

The following error screen pops up,

The NTVDM CPU has encountered an illegal instruction
CS:0769v IP:02d2 OP:ff ff 00 00 00 Choose ‘Close’ to terminate the application.

There is a ‘Close’ and ‘Ignore’ button.

If I choose ‘Close’ the command prompt window will quit immediately.

If I choose ‘Ignore’, it brings up another 8 NTVDM CPU messages just with value changes in the description. I had to End Task the Command Window.

I have looked up various search engines and Microsoft, I have found similar errors but nothing specific to my problem.

Has anybody encountered problems like this with Cobol and Windows 2000?

Although I am using MicroFocus Cobol, I had the same problem.
Create a partition on your HD exclusively for Cobol.
This must be a FAT partition, not FAT32 or NTFS.
Copy all your Cobol-stuff, such as the compiler, source-files, EXEs etc. to that partition and RUN your Cobol-programs from there in a DOS-window. My compiler is so old (1985!) -as may be yours- that it only works on a FAT partition.
HTH

I'll try that on an older PC that I have and see if it works. I wont be able to run the cobol program through DOS and it is a precompiled piece of software. Thanks for your assistance.
