Problem summary

• ****************************************************************
  * USERS AFFECTED: Enterprise PL/I users of the macro           *
  *                 preprocessor with code containing heavily    *
  *                 nested %IF statements                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: Enterprise PL/I has a limit of 100 for  *
  *                      the nesting of %IF statements.          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  With the introduction of the %SELECT statement, it would be
  better to change heavily nested %IF statements to %SELECT
  statements. But the limit on the nesting of %IF will be
  increased so that more old code will compile ok
  

Problem conclusion

• With this PTF, the limit on the nesting of %IF statements has
  been increased to 200
