Problems addressed in this kit

      o  The logical DTR$DATE_INPUT did not handle four digit years correctly.
	 For example, if the logical was set to "MDY" and a date string was
         input in the following format - 12311999 - a conversion error was
	 reported. This problem has now been fixed, and the correct date (i.e.
	 31-DEC-1999 in the example) will be returned.

      o  DTR supports several formats of date field on its forms. These
         include 2-digit and 4-digit year date formats. DTR validates date
         fields and translates all date fields formats into the standard
         OpenVMS binary date format which is then passed to the application.

         In order to successfully translate 2-digit year date fields into their
         corresponding binary format, DTR has to supply the missing 2 digits
         of the year (i.e. the century digits). DTR has always used the
         century digits as specified by the system clock. This is entirely
         consistent with the way that incompletely specified dates are
         interpreted in OpenVMS.

         At the turn of the century, the behavior of DTR as described above
         will mean that 2-digit year dates from the screen will be interpreted
         differently. All 2-digit year dates will be processed as being in the
         21st century, exactly 100 years later than previously.

	 DTR now uses a so-called sliding window capability for the
         translation of DTR 2-digit year dates.

         This enhancement will allow for the modification of the behavior of
         DTR so that the century digits applied to a 2-digit year date may be
         based on a customer specified value.

         On each occasion DTR is required to expand a 2-digit year date it
         will attempt to translate a logical name called DTR$BASE_YEAR. Valid
         values for this logical name are 4-digit numbers in the range 1859 -
         9900. DTR will search the PROCESS table followed by the GROUP table
         and finally the SYSTEM table and will use the first valid value found.
         If no valid translation of the DTR$BASE_YEAR logical is found then
         the behavior of DTR in processing 2-digit year dates will remain
         exactly as in the current version of DTR.

         This 4-digit number resulting from a valid translation of the
         DTR$BASE_YEAR logical name is used by DTR to define the first year
         of a 100 year window in which all 2-digit year dates fall. For
         example a value of 1980 defines a 100 year date window of 01-JAN-1980
         to 31-DEC-2079.

         Customers who wish to have DTR continue to translate 2-digit year
         dates in the 20th century should set the DTR$BASE_YEAR logical to
         the value 1900 while customers who wish to have DTR behave exactly as
         before should not define the logical name.


This ECO also includes the following fix from DTRAXPECO01072:
      o  This kit fixes a problem in the Report Writer. When the
	 AT TOP OF REPORT clause was executed, no output for the
	 desired literal occurred.


Installation Instructions:

     Install this kit with the VMSINSTAL utility by logging into the
     SYSTEM account, and typing the following at the DCL prompt:

         @SYS$UPDATE:VMSINSTAL  DTRAXPECO02072 [location of the saveset]

     The saveset location may be a tape drive, or a disk directory that
     contains the kit saveset.
