PH37330: COBOL COMPILER FAILS TO DIAGNOSE 2 WHEN PHRASES IN A SEARCH ALL STATEMENT AND GOES INTO A LOOP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• COBOL compiler fails to diagnose 2 WHEN phrases in a SEARCH ALL
  statement and goes into a loop
  

Local fix

• Do not code 2 WHEN phrases
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.3 who           *
  *                 accidentally code 2 WHEN phrases in a nested *
  *                 SEARCH ALL statement.                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: The compiler will get into an infinite  *
  *                      loop, and not put out a diagnostic      *
  *                      error message.  If 2 WHENs are in a     *
  *                      non-nested SEARCH ALL, the compiler     *
  *                      correctly diagnoses the error, but not  *
  *                      if the 2 WHENs are coded for a SEARCH   *
  *                      ALL nested in another SEARCH ALL.       *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler got confused parsing the nested
  SEARCH ALL and failed to diagnose the error and tried to
  generate code for an impossible case.  (Only 1 WHEN is allowed
  in SEARCH ALL statements).
  

Problem conclusion

• The compiler was changed to correctly diagnose the
  second WHEN and prevent the back end from trying to generate
  code for a defective program.
  

Temporary fix
