Allow z/OS C/C++ library to write zero-length data set records using record mode processing.

The z/OS C/C++ library will currently not allow the creation of zero-length records using record-mode processing using fwrite(). This applies to RECFM=V*, and RECFM=U. It is possible using text mode, but this does not allow for binary processing. It is also possible using "blocked" mode, but this requires that the application support the formatting of blocks for all record/block formats including VBS, LRECL=X, etc. It *is* possible to read zero-length records in record mode using the C/C++ library.

    This item is a valid requirement but unlikely to be given high enough priority to be placed into the product plan. If this requirement is high value, please re-open it, or open a new requirement.

    I forgot to mention that the current limitation also impacts z/OS Java users who use the JZOS toolkit, since the "ZFile" class is a wrapper for the C/C++ library. In other words, using JZOS ZFile it is currently not possible to write zero-length records to a binary RECFM=U/V* data set.
