- The October 2007 and the November 2007 versions do not evaluate DATA_RANGE= in the CORRECT step. The August 2007 version, and versions since December 2007 do.
- The June and July 2008 versions of "xds_par" under Linux suffer from a compiler bug in the CORRECT step: the correlation coefficient against a reference data set is always 0.00, and therefore sometimes the wrong decision is made concerning re-indexing of the data. Example taken from CORRECT.LP produced with xds_par:

The workaround is to use the single-processor version ("xds") instead.
