PH39966: JSON GENERATE DOES NOT HONOR THE TRUNC(BIN) COMPILER OPTION AND INCORRECTLY REQUIRES DATA TO FIT INTO THE PICTURE CLAUSE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With TRUNC(BIN), a JSON GENERATE of a 5-digit data value into a
  PIC S9(4) BINARY data item truncates the high order digit,
  moving only the lower 4 of the 5 digits into the receiving field
  (i.e. it aligns at the decimal point and then the left-most
  digit is truncated).  TRUNC(BIN) does not seem to be honored
  with JSON GENERATE and the data is truncated to fit into its
  picture clause.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling     *
  *                 and running programs containing the JSON     *
  *                 GENERATE or XML GENERATE statement with the  *
  *                 TRUNC(BIN) compiler option in effect.        *
  ****************************************************************
  * PROBLEM DESCRIPTION: In some cases the generated XML and/or  *
  *                      JSON may contain numeric values that    *
  *                      do not respect the TRUNC(BIN)           *
  *                      truncation rules when the TRUNC(BIN)    *
  *                      option is in effect..                   *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  In some cases the compiler was generating code that did not
  respect the TRUNC(BIN) option in cases where the XML GENERATE
  and JSON GENERATE statements were producing output from numeric
  COBOL data items.
  

Problem conclusion

• The compiler was changed to generate the correct code.
