FL5 - Change Log

FL5 - 5.1.11 (Released 2016-04-01) View Issues ]
==================================


 * Add support for ZIP archives of version 2.0 (no encryption)
 ** Add redundancy detection (automatically skips compression if no redundancy is found)
 ** Use FIO.ZIP() in conjunction with CNV.ZIP() via XCNV command to read and write compressed ZIP archives
 *** Without CNV.ZIP() files are stored uncompressed
 ** The format version required to read the written ZIP archives is 2.0
 ** DEFLATE and BZIP2 compression are supported
 ** Encrypted ZIP archives are currently not supported (workaround: store encrypted PGP files in the ZIP archive)
 ** UTF-8 and ZIP64 are supported to allow archives larger than 4 GiB
 ** The extra field is used to store important file attributes (DCB parameter) for ZIP archives and GZIP files
 * Add FLAM4 record interface support for Microfocus EDZ on Windows and Linux
 ** Develop host-compliant COBOL programs using FLAM4 record interface on Windows and Linux
 ** Supports only sequential I/O (no insert, delete, update, search)
 ** Usable also with FLCL utility and subprogram for FLAM4FILEs known by MF-EDZ catalog
 ** Works like data set and DD name support under USS for MVS ('DD:name' or //'data.set.name')
 ** Add new FL4REC documentation in DOCZIP and DOCPDF (valid for all platforms)
 * New formatting method format.element() available in FLUC byte and record interface
 ** Allows reading and writing of raw FLAM5 elements
 ** Provides the matrix type, element type, attributes, element data and hash values for each element
 ** Useful for example to get access to parsed XML elements
 ** New sample programs in C (SCFCBELM, SCFCBDOM) and COBOL (SOFCRXML)
 ** See byte/record interface API docu for details
 ** Add Cobol sample SOFCREXV for it
 * Add element conversion capabilities to byte and record interface if format.element() is used
 ** Several conversions can be applied to elements read or written elements
 ** Conversion modules can be opened and then passed to the read and write functions to apply the conversion
 ** Usage example: Convert XML elements to integers / floating point numbers or collapse strings (remove whitespace)
 * XML data elements read via the element formatter now contain larger data chunks than before (i.e. data in tag body is split less often)
 * DTD XML elements and DEFAULT elements can now be suppressed when reading by using the NODTD or NODFLT switch, respectively
 * New WllFmd switch when writing XML to verify that the XML document output is well-formed XML
 ** Useful if format.element() is used on byte or record interfaces
 * Add FCRLOC to record interface (fcbread() with size==-1)
 ** Reads records or elements and returns a pointer to a record or to an element structure and its length
 ** Improves performance and makes variable length data more simple to handle
 * Add fcbprev() function to FLUC byte and FCRPRV to record interface
 ** Sets the read position to the previous record or element
 ** Can be used, for example, to simplify scanning of elements or to place back the last read byte/character (implemented as fcbungetc())
 * Add FCRFLU to FLUC record interface to flush buffered content
 * Add fcbgetc(), ungetc(), putc(), gets(), puts(), clearerr() functions to FLUC byte interface
 ** Most common functions known from the C runtime are now available
 * Add matrix type to state string of byte and record interface
 * Add data type and format to state string in byte and record interface (only returned when reading, not required when writing)
 * Correct syntax for input and output file string for FLUC stream, byte and record interface
 * Correct manpages and help information for FLUC stream, byte and record interface
 * Correct logic of the DECODE parameter of read.char() and read.text()
 * Add log message to FLUC about GZIP/ZEDC on open platforms
 * Improve performance and memory consumption of the PGP component
 * Add log format MINIMAL which prints log messages without any prefix
 * Add log type OUTPUT to separate output values (for example checksums)
 * Add HEX/BIN formats and CUT parameter to get sub-hash values to CNV.HSH() component
 * Unmask last parameter in load modules to prevent wrong length calculation and other possible mistakes
 * Significantly improved API documentation in Doxygen HTML pages
 ** Improved the general structure and completeness of descriptions
 ** Better layout
 ** New appendix for format and state strings of FLUC byte and record interface
 * Add support for reason codes to FLUC subprogram interface (FLUCUP)
 * Add user table for character conversion to read specifications of CONV command to support subset validation at read
 * Add file name mapping for GZIP and OpenPGP header
 * Make ASCII-Armor header available in all cases when writing
 * Fix segmentation fault if only an empty record was written via record and byte interface before closing the file
 * Support member name as explicit parameter in write.flam()
 * Command line processor (CLP) accepts integers as floats if a float is expected
 * Add LBI Support (tapes with large blocks) in FLAM4 for z/OS
 * Support HEADER=NO in FLAM4-Subsystem (no member headers for files in FLAM4 archive)
 * Increase internal record length by delimiter length in FIO.REC() when writing to prevent record length errors
 * Fix wrong CCSID and CHRSET in FIO.FL4() if the old translate parameter was used
 * Ensure that SKPNOB works for CNV.BAS() without auto detection and format error is given
 * Add generated copy books for FLUC record (SOFLCREC) and subprogram interfaces (SOFLUCUP) to SRCLIB
 * Length format specification with system endianess now works correctly (was always little endian)
 * Fix FLAM4 error messages for system errors
 * Significantly reduce memory consumption of the CLEP
 * GRAVE ACCENT (` - U-0x0060) to enclose strings is now supported by the command line processor
 ** Useful on some platforms to specify strings in strings, e.g. for FKM5 parameters
 * Correct dynamic allocation of UNIX pathnames on z/OS in FIO.FL4()
 ** FLAM4FILEs are now allocated correctly in USS if FLCL is used
 * CNV.PGP() now returns a format error if an internal buffer too small for remaining rest data
 ** This can only occur if something is wrong with the PGP file format
 * Correct use of CSFKDSL in FKM5-PGPCCA to provide PKDS only solution without key store parameter
 ** Requires z/OS 2.2 or update to ICSF FMID HCR77B0
 ** Resolves the log issue because a direct VSAM locate against the PKDS beside ICSF is not longer required
 ** With this solution the FKM5 object is not longer required if you write PGP files with ICSF
 * Fix error (ISSUE 797) in PGP module which result in raw cases in a rest buffer overflow or format error
 * Use canonical path for member names at write of FLAM4FILEs with FLUC
 * Support of slot numbers (RRDS), ASA and machine control character at read with record conversion and formatting
 * Support write of attributes in front of records at block conversion and formatting
 * Support attributes (ASA, MCC, ...) if text formatting used at write with method record
 * Info function detects now empty files (not mark as binary file anymore)
 * Integrate FLVIEW into FLTOC ISPF panels of FLAM4 on z/OS (supports V character for it)
 * Implement workaround for ZEDC firmware bug (PMR) for FLAM4FILEs
 ** The ZEDC need few bytes more output buffer for decompression than input was given at compression
 ** FLAM4 provides now 4 byte more output buffer to solve this issue
 ** IBM plan to fix this bug within the next firmware version of the card
 ** Our implementation is now independent of the ZEDC firmware version
 * Improve detection of files smaller than the given block size
 ** In raw cases the PGP module gives an error to increase the block size
 ** But if the whole file smaller than this block size this makes no sense
 ** In this case a format error is now returned to better support the transparent read
 * Use FMT.BIN() as default at write if FMT.REC() used at read to keep the records
 * Use FMT.BIN() as default at write if FMT.BLK() used at read to keep the blocks
 * Fix segmentation fault in CNV.GZP/BZ2/LXZ() if memory allocation failed
 * Fix error at reorganization of ZIP files if a static allocation for the ZIP file used on z/OS
