Chapter 19 Pg 59      DSZ Reference Rev May-29-93        Typeset 5-29-93


     20.  CHANGES

     Be sure to save your serial number/password (SNP) card and the putsnp
     program you received from Omen Technology to use with future versions of
     DSZ you may download!  (Use GCOLORS to serialize GSZ.)

     Current GSZ and DSZ versions are maintained on EXEC-PC BBS, BIX, GEnie
     (IBM Roundtable), CompuServe (IBMCOM and CONSULT SIGs) as well as Omen's
     TeleGodzilla (503-621-3746).

     DSZ is a popular program which has been the object of virus attacks.
     Pirated/hacked versions of DSZ have cost users and DSZ's developer
     thousands of dollars in lost time and other expenses, in addition to
     injuring of Omen Technology's reputation.

     Virus and Trojan code hidden in hacked/pirated copies of DSZ and
     programs claiming to "register DSZ" have caused loss of data.

     Your copy of should show the same CRC values.  ZIP uses a 32 bit CRC
     compatible with the Professional-YAM and ZCOMM "crc" command.
           pkzip -vt dsz
     The following Pro-YAM/ZCOMM command gives the 32 bit CRC for DSZ.COM:

     EXAMPLE: >>>c: crc dsz.com


     If your copy shows a different CRC or file length, insist on a
     legitimate copy and report the source of the bogus/pirated copy to Omen
     Technology Inc.  Omen Technology has received reports of serious
     problems caused by unauthorized patches to DSZ, and cannot assume
     liability for the performance of the resultant code.


     COM7 and COM8 are changed; see the "port" command above.

     A problem in the 1/17/89 and 2/2/89 DSZ versions corrupts files under
     unusual circumstances.  Please delete all instances of the 1/17/89 and
     2-02-89 version.
