This is 14/12/2001 version of the comparison program. It allows: - checking of vienna datafiles. File "a.txt" generates an "a.txt_rep" file - generation of vienna files conform with annex2bis (automatically when checking) generates an "a.txt_annex2bis" file. - comparison of two vienna files Most of the remarks of the 3-5 dec Berlin reunion have been implemented. Installation is by running setup.exe I have successfully installed this on two computers, so it should work. Microsoft recommends that if installation fails, you install the dcom98.exe file.
