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 V6.2 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.
