data. As of BS2000/OSD-BC V6.0, a new system behavior will

therefore be introduced with which the default value of the CCS

name of a file is determined.

Note:

ISO8859-x variants should not be used as a system or user

character set since all programs in BS2000 assume that the

data is provided with a so-called invariant EBCDIC core.

Previous behavior:

Up to BS2000/OSD-BC V6.0B, the BS2000 system always assigns the

default *NONE for the CCS name of the file (CCS-Name=*NONE). If

a different character set is used, the file attribute CCS name

must be specified explicitly.

Changed behavior:

The two commands CREATE-FILE and MODIFY-FILE-ATTRIBUTES have

been extended by the parameter *USER-DEFAULT that defines the

default character set for the ID concerned.

If it is not EDF03IRV, when a new file is now created the CCS

name of the user entry of the destination pubset is taken over

as the CCS name of the file. As previously, the file does not

receive an entry for the CCS name (CCS-Name = *NONE) if EDF03IRV

is in the user entry. The file attribute CCS name is included in

the transfer when copying, saving and restoring files. The

behavior of LMS has also been changed analogously when new

elements are added. If a CCS name is not explicitly specified,

they are assigned the CCS name of the library.

There is therefore no change if the default system character set

is used. If an 8 bit character set is selected, the code is

clearly specified on the file and library element level via the

CCS name. However, explicit specification of the character set

always has priority.

You will find further information on converting from 7 bit to 8

bit character sets in the white paper under

2.16.3 New ASTI Subsystem

ASTI (Assistant for Service Task Integration) is implemented as

a subsystem and provides support for the system developer when

developing client / server applications. ASTI takes over the

communication between client and server by forwarding the orders

placed by the client to the server, receiving the feedback

messages and managing both in internal ASTI wait queues. A

server application must be started via ASTI to allow it to be

managed by ASTI. It is also possible to specify for client

orders whether recovery measures are to be initiated for the

orders concerned if the server terminates prematurely.

The ASTI functions are made available to the developer via a

macro interface.

ASTI is part of the BS2000/OSD basic configuration and is

initially only released for internal use by BS2000 products.

The first user of ASTI is the product interNet Services V3.2.

The ASTI subsystem is started automatically when the system is

booted.

You will find a detailed description of ASTI in the file
