You can debug 32- or 64-bit programs that are running on a different computer from the one on which you are using to develop COBOL.
Either Visual COBOL or COBOL Server needs to be installed on the remote computer.
To debug remotely, the two systems must be networked using TCP/IP and must be set up appropriately.
