PI63281: (COB V6.1) WITH DEBUGGING MODE ENABLED, MODULE SIZE IS 4 TIMES GREATER THAN V4.2 MODULE SIZE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• (COB V6.1) With debugging mode enabled, the module size is 4
  times greater than the V4.2 module size.  Modify the compiler
  to reduce the module size where feasible.
  

Local fix

• Compile with debug mode turned off.
  

Problem summary

  ****************************************************************
  The V6 COBOL compiler was generating less efficient code to
  handle the USE FOR DEBUGGING declarative then the pre-V5 COBOL
  compilers.
  

Problem conclusion

• The V6 COBOL compiler was generating less efficient code to
  handle the USE FOR DEBUGGING declarative then the pre-V5 COBOL
  compilers.
