PH02398: CORRECT LEVEL-88 TEST TO YIELD A FALSE RESULT WHEN THE "WHEN SET TO FALSE" CLAUSE & "SET CONDNAME TO FALSE" IS USED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a user adds a WHEN SET TO FALSE clause to a condition-name
  (level 88 data item) description, and then uses
  SET condname TO FALSE, the condname will still test as TRUE.
  
  This APAR will correct the compiler to test for the correct
  TRUE values when using condition-names that have WHEN SET TO
  FALSE.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.2 compiling and  *
  *                 running programs that have been modified to  *
  *                 take advantage of the feature 'WHEN SET TO   *
  *                 FALSE' for condition-name (level 88) data    *
  *                 item definitions.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a 'WHEN SET TO FALSE' clause is    *
  *                      added to a condition-name definition    *
  *                      and the condition-name is then tested,  *
  *                      the value tested for is the FALSE       *
  *                      value instead of one of the true        *
  *                      values.                                 *
  ****************************************************************
  * RECOMMENDATION: Install provided PTF and recompile.          *
  ****************************************************************
  When a 'WHEN SET TO FALSE' clause is added, the compiler
  incorrectly generates code to test for the FALSE value when
  testing for a true value.
  

Problem conclusion

• The compiler is corrected to test condition-names for correct
  TRUE values, even when WHEN SET TO FALSE is specified.
