                          AST-3270/FTS-C FUNCTIONAL ISSUES

    AST Product Marketing has reviewed all of the open issues relating to this
    product.  They have made the decision that the following issues will not be
    resolved.

    This product has been discontinued by AST.  No further enhancements will be
    made to this product.

    These issues are:

        - User cannot upload files to a TSO host properly.  If the customer tries
          to upload information to an existing partitioned data set and a non-
          existing member, he receives the error message "UNABLE TO TERMINATE
          INPUT MODE".  If neither the data set nor the corresponding member
          exist on the host, the file transfer will work for the first member
          only.  (PR#A32006)

        - User cannot transmit more than one file to the host during a file
          transfer session.  The first file transfers okay, but after entering
          the second file name, the error message from the host "IKJ56712I-
          INVALID KEYWORD, LISTDS IKJ560703A-RE-ENTER" is displayed.  The file
          transfer software displays the message "Unable to open dataset".
          (PR#A32007)

        - With FTS-C version 1.31, user is reporting intermittent problems when
          attempting to upload files of greater than 64K in size.  The host is an
          IBM 4381 running CMS under VM/SP release 5.  When FTS-C attempts to
          close the uploaded file, the error message "NON-RECOVERABLE HOST ERROR,
          FTS ABORTED" is displayed.  (PR#A32011)

        - When attempting file transfer on an MVS/XA TSO/ACF2 host, the error
          message "Unable to list TSO profile" message is received when the file
          upload is commenced.  (PR#A32012)

        - When performing file uploads to the host, user says that FTS-C sends
          screens of data faster than the host can process them.  The software
          does wait for an acknowledgement from the host that the first screen
          was received, but does not wait to send ensuing screens of data.  The
          host is operating under MVS/XA TSO.  (PR#A32013)

        - When using FTS-C software with a mainframe configured with TSO/E
          version 3.0, downloading of files does not occur correctly.  Parts of
          records are either truncated or missing altogether.  Problem occurs
          with files of larger than 10K in size.  (PR#A32008)

        - "Unrecoverable host errors" occur on a host operating under VM
          release 5 with a multi-session manager called "VTERM" installed.
          Errors occur at end of file transfer session as files are being
          downloaded.  (PR#A32014)

        - Packed record formats are not supported with FTS-C.  When the
          software encounters the LRECL parameter value of "1024" (for packed
          files) the error message "record length greater than 255" is
          generated.  (PR#A32015)
