PI89861: Invalid code coverage reported in RDz, hints in COBOL LIST option output are incorrect for empty blocks like ELSE CONTINUE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an ELSE block is empty save for a CONTINUE or NEXT
  STATEMENT statement, the SNAPSHOT FALSEIF hint appears after the
  END-IF label, causing the code coverage tool to always mark both
  the THEN and the ELSE branches of the IF taken.
  

Local fix

• Where possible, remove the empty block
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users debugging modules compiled with        *
  *                 Enterprise COBOL V5.2 containing an ELSE     *
  *                 clause with only a CONTINUE inside it.       *
  ****************************************************************
  * PROBLEM DESCRIPTION: Debugger may show that both the true    *
  *                      and false path are taken on an IF       *
  *                      clause.                                 *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The ELSE clause containing only a CONTINUE was seen as empty
  and seen as the code following the IF condition.
  

Problem conclusion

• Compiler was updated to properly keep track of an empty ELSE
  clause.
