PH23462: INCORRECT IGYPS2113-E AND IGYPS2112-E ERRORS IN A COMPILE WITH A VERY DEEPLY NESTED COMPLEX IF STATEMENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The compiler can lose track of the number of deeply nested
  complex IF-ELSE statements when the nesting exceeds 100+,
  resulting in incorrect IGYPS2113-E and IGYPS2112-E errors.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the z/OS Enterprise COBOL       *
  *                 Compiler V6.2, whose source programs contain *
  *                 deeply nested and complex IF statements.     *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect output:                       *
  *                      The compiler may produce confusing and  *
  *                      possibly erroneous IGYPS2113-E and      *
  *                      IGYPS2112-E error messages.             *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  When processing deeply nested and complex IF statements, the
  compiler was losing track of the nesting level. This resulted
  in erroneous IGYPS2113-E and IGYPS2112-E error messages because
  the compiler was losing count of IF .. ELSE statements and
  dropping and/or adding END-IF statements.
  

Problem conclusion

• There was a minor problem in the part of the compiler that
  tracks the nesting level of deeply nested and complex IF
  statements. A correction has been made to the compiler, so
  that the table management code where this nesting level is
  being tracked, will always be correct.
