PM87730: STRATIFICATION REPORT PRECISION FIELD OVERFLOW FOR IMU 4.1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Per IMU 3.20 PMR 01414,379,000 - Stratification report PRECISION
  field overflow
  ================================================================
  Date reported: 04/03/2013
  
  Severity: Medium
  
  Users Affected:
   All IMU users of MU V4.1
  
  Problem Description:
   The PRECISION_ value printed on the Stratification report is
   negative.
  
  Problem Summation
   The PRECISION_ field is defined as a 4 byte binary field with
   two decimal places. The maximum value that can fit into a BL4
   signed integer with two decimal places is 21,474,836.46. Field
   overflow is caused when Precision value coded on the STRATIF1
   macro exceeds 21,474,836 resulting in unpredictable outcome.
  
  Problem Conclusion:
   A change was made to STRATIF1 macro to define PRECISION_ as a
   PL7 instead of BL4 field. The change was made   conditionally
   as follows:
    1. If PRECISION_ is a number less or equal to 21,474,835, the
       field is defined as a BL4 field.
  
    2. If PRECISION_ is a number greater than 21,474,835, the
       field is defined as a PL7 field.
  
    3. If PRECISION_ is a field name, the field is defined as a
       PL7 field regardless of the size.
  
  
  Impact on the REPORT layout
   The PRECISION_ field is printed on the TITLE 4 of the
   Stratification report. When PRECISION_ size is increased to
   PL7, the PRECISION_ field value will be printed 4 positions to
   the right as shown below.
  
   The old way:
    ---5----+----6----+----7----+----8----+----9----+----0
    PRECISION: 21,474,835.00    CONFIDENCE:90%
  
   The new way:
    +----5----+----6----+----7----+----8----+----9----+----0
    PRECISION:     21,474,837.00    CONFIDENCE:90%

Problem conclusion

• A change was made to STRATIF1 macro to define PRECISION_ as a

   1. If PRECISION_ is a number less or equal to 21,474,835, the
  
      field is defined as a BL4 field.
  
   2. If PRECISION_ is a number greater than 21,474,835, the
      field is defined as a PL7 field.
  
   3. If PRECISION_ is a field name, the field is defined as a
