These values are identical to the ATR$C_XXXX and             ATR$S_XXXX constants which are defined in ATR.H under             OpenVMS C.  Neither of these values will ever be zero.          2. No word alignment or padding is performed.          3. A well-behaved PKZIP/OpenVMS program should never produce             more than one sub-block with the same TagX value.  Also,             there will never be more than one "extra" block of type             0x000c in a particular directory record.         -Info-ZIP VMS Extra Field:          ========================          The following is the layout of Info-ZIP's VMS attributes extra          block for VAX or Alpha AXP.  The local-header and central-header          versions are identical.  (Last Revision 19960922)          Value         Size        Description          -----         ----        -----------  (VMS2)  0x4d49        Short       tag for this extra block type ("JM")          TSize         Short       total data size for this block          ID            Long        block ID          Flags         Short       info bytes          BSize         Short       uncompressed block size          Reserved      Long        (reserved)          (var.)        variable    compressed VMS file-attributes block          The block ID is one of the following unterminated strings:                "VFAB"          struct FAB                "VALL"          struct XABALL                "VFHC"          struct XABFHC                "VDAT"          struct XABDAT                "VRDT"          struct XABRDT                "VPRO"          struct XABPRO                "VKEY"          struct XABKEY                "VMSV"          version (e.g., "V6.1"; truncated at hyphen)                "VNAM"          reserved          The lower three bits of Flags indicate the compression method.  The          currently defined methods are:                0       stored (not compressed)                1       simple "RLE"                2       deflated          The "RLE" method simply replaces zero-valued bytes with zero-valued          bits and non-zero-valued bytes with a "1" bit followed by the byte          value.          The variable-length compressed data contains only the data corre-          sponding to the indicated structure or string.  Typically multiple          VMS2 extra fields are present (each with a unique block type).         -Info-ZIP Macintosh Extra Field:          ==============================          The following is the layout of the (old) Info-ZIP resource-fork extra          block for Macintosh.  The local-header and central-header versions          are identical.

The least          significant bit of Flags is 1 if the file is a data fork, 0 other-          wise.  In addition, if this extra field is present, the filename          has an extra 'd' or 'r' appended to indicate data fork or resource          fork.  The 28-byte VolName field may be omitted.         -ZipIt Macintosh Extra Field (long):          ==================================          The following is the layout of the ZipIt extra block for Macintosh.

This variant is used by ZipIt 1.3.5 and newer for entries of          files (not directories) that do not have a MacBinary encoded          file.  The local-header and central-header versions are identical.

This variant is used by ZipIt 1.3.5 and newer to          save some optional Mac-specific information about directories.          The local-header and central-header versions are identical.
