Bug fixes

Changes in opensource COBOL v1.3J

New features

• Unicode (UTF-8 encoding) support. Add --enable-utf8 option to 'configure' parameters to activate. Without the option, SHIFT-JIS support is default for the configure. The features of Unicode support are:
  1. allocate 3 bytes for single 'N' in PICUTURE clause.
  2. unit of arguments in reference modification and parameter values in INSPECT statement are bytes (not a count of characters).
  3. padding blank by half-with (1 byte for each) spaces.
  4. suppress check for mixed full-witdth/half-width char. strings in STRING statement parameters.
     !! These semantics of the UTF-8 support may change in the future. !!
• Support some of COBOL dialect and unsupported statements/functions frequently used in existing COBOL program assets.
• SPLIT KEYS (for VBISAM) based on the article on The OpenCOBOL Project FORUM.
  Thank you! the author Mr. JoeRobbins and The OpenCOBOL Project.

• add option to enable function NATIONAL.
  (enable-national-intrinsic-function in conf. setting)
  A default settings of these parameters is "no".

Changes

• now currency symbol can be changed in conf. setting.
  (default-currency-symbol)

Bug fixes

• invalid adress reference in external file handler (USERFH) (only occurs in 64bit environment).
• wrong line number in compilation messeages when -free_1col_aster is applied.
• failure in reference modification at NATIONAL EDITED field.
• internal error on Japanese string in PROGRAM-ID.

Changes in opensource COBOL v1.2J

• Support Feature of Japanese, such as constant and definition of data and operation of data.
• New compile option '-assign_external' and variable 'assign_external=[yes|no]'. Set the file assign to the EXTERNAL file.
• New compile option '-free_1col_aster'. In free format COBOL mode, this option causes the compiler to regard as line comment when first column is asterisk for free format COBOL mode.
• New runtime environment variable OC_USERFH, which enable to run user-defined program in operation OPEN, CLOSE, DELETE, READ, REWRITE, START, WRITE, COMMIT, ROLLBACK and UNLOCK.
• Support currency symbol for Japanese yen, and modify default currency symbol to Japanese yen.
• Changed to apply the alphabetic manner as comparison method in case its operands include group fields.
• Fixed the problem that INSPECT causes incorrect result in case given the AFTER/BEFORE clause with negative value or SIGN SEPARATE field.
• Fixed the problem that value comparison on SIGN SEPARATE fields in IF or EVALUATE statements fails treating such field values as if their sign character were a part of digits.
• Fixed the problem that applying INITIALIZE on 01-level records in EXTERNAL files causes incorrect behavior of following I/O instructions.
• Changed the default actions on unhandled SIZE ERROR according to that specified in Programmer's Guide.
• Fixed the problem that applying INITIALIZE or MOVE ZERO on numeric field of SIGN SEPARATE destroys sign byte.
• Fixed the problem that COPY statement ignores the last line of each copybook when it does not end with line break.
