PH70633: CONSIDERABLE CPU INCREASE FROM COBOL V6.3 TO COBOL V6.4/V6.5 IN A MOVE STATEMENT WITH ARCH(14)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Programs compiled with Enterprise COBOL V6.4/V6.5, and ARCH(14),
  that contain a large number of MOVE statements converting data
  from USAGE DISPLAY fields to numeric edited fields have worse
  runtime performance than Enterprise COBOL V6.3. The compiler
  generated inefficient instructions when converting from a USAGE
  DISPLAY to a Numeric Edited, resulting in slower performance.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.5 compiling      *
  *                 programs at ARCH(14) and above that contain  *
  *                 a large number of MOVE statements converting *
  *                 data from USAGE DISPLAY fields to numeric    *
  *                 edited fields.                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Program may have worse runtime          *
  *                      performance than Enterprise COBOL 6.5   *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF                       *
  ****************************************************************
  The compiler generated inefficient instructions when converting
  from a USAGE DISPLAY to a Numeric Edited, resulting in slower
  performance.
  

Problem conclusion

• The compiler was updated to produce optimized instructions for
  above conversion when compiled with the NOINVDATA option.
