Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V5 or later        *
  *                 releases running programs that use INSPECT   *
  *                 statements with BEFORE or AFTER phrase.      *
  ****************************************************************
  * PROBLEM DESCRIPTION: If the delimiter in the BEFORE or AFTER *
  *                      phrase has more than one character,     *
  *                      and the first character is repeated     *
  *                      contiguously in the item being          *
  *                      inspected, performance may be slower    *
  *                      than other common inspect scenarios.    *
  *                      (Refer to Problem Summary below for an  *
  *                      example of the INSPECT statement.)      *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF provided.                      *
  ****************************************************************
  The string comparison method used to check BEFORE and AFTER
  delimiter is not optimized for repeat characters in the
  inspected data item (i.e. ITEM1 in the sample below). The code
  fragment below shows an example of such a case. The repeated
  "A" in ITEM1 causes the COBOL library routine to do unnecessary
  checking during string comparison.
  -----------------------------------------------------
  01 ITEM1 PIC X(80) VALUE
     "THIS IS AAAAAAAAAAAAAAAAAAAAAAAAAATEST".
  01 TALLY1 PIC 9(8).
  INSPECT ITEM1 TALLYING TALLY1 FOR
          CHARACTERS BEFORE 'ABCD'.

Problem conclusion

• BEFORE and AFTER processing of the COBOL library INSPECT routine
  has been improved.
