The fix contained in the file  date_precision will modify the
SAS/ACCESS to Informix engine so that DATETIME precision values such as 
DATETIME year to year, DATETIME year to month, DATETIME year to day, 
DATETIME month to anything and DATETIME day to anything are 
automatically extended by SAS. 

To install this fix: 

1)  cd to your !SASROOT/sasexe directory.
2)  Rename the existing sasionfx executable to a new name such 
    as sasionfx.orig.
3)  Transfer the date_precision file to your machine using a binary 
    transfer method.
4)  Rename the date_precision file to sasionfx.  The permissions for 
    this file must be 755.
