i guess that the column numbers to which you refer are in the input data set to CLCOR.  Therefore the issue is not with CLCOR but with DELZN that wrote that text file.  Since I believe that DELZN is working properly, There must be something about your data that has caused it to produce unusable values for the time derivatives.  I have no idea what your data are or why such a problem could happen.  You will need to examine your data more closely to discover what has caused DELZN to go wrong.  Of course you could replace columns 8 and 9 with zeros and get the benefit of the good delay corrections without added error from the derivatives.  (Or after CLCOR you could use TABPUT to zero out the derivative columns in the CL table.)
