PH68453: CONSIDERABLE CPU INCREASE FROM COBOL V6.3 TO COBOL V6.4/V6.5 IN A MOVE STATEMENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Programs compiled with Enterprise COBOL V6.4/V6.5 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.

  ****************************************************************
  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.
