I have added the DCOL routine to the prode.dll. You may find the updated prode.dll and a test file for the DCOL routine on my website.
The dll was built to handle VLE, VLLE, and LLE columns. Only VLE option is available to Prode users with Basic license. I have the Basic license, so I am unable to test the dll for the other two cases. Please let me know if there appears to be a problem with the dll for the VLLE or LLE options.
