Can Tersedcompress output the data set type of the original dataset?

Open travatine opened this issue 5 years ago • 1 comments

Hi, Tersed compress is great, I was wondering if it'd be possible to display the orginal data set type ? i.e. was it a PS / PDS or PDSE ?

Thanks

as far as i see, we only have RECFM, LRECL and the host type. I can suggest it might be in the flags section of header, but the format is closed and we only aware of :

    /*
     * These appear to be the flags for the terse file header. Some are used by 
     * CheckHeader() others are only used when writing a compressed file which
     * this implementation doesn't do.
     */
    static final int  FLAGUNDEF = 0x80;       /*  \                                                    */
    static final int  FLAGCC1   = 0x40;       /*   \                                               */
    static final int  FLAGCC2   = 0x20;       /*    \                                              */
    static final int  FLAGVBS   = 0x10;       /*     >-- values of Flags bits in HeaderRecord type */
    static final int  FLAGVS    = 0x08;         /*    /                                              */
    static final int  FLAGMVS   = 0x04;      /*   /                                               */
    static final int  FLAGRBITS = 0x03;       /*  /                                                */

Closing, will reopen if any more info found
