Abstract

Connecting unlike systems is a major development activity and different communication protocols such as APPC are developed for transferring data between these unlike systems. The code pages for these systems are in most cases different and a data conversion is needed from one code page to the other while transferring data. The current implementation requires the user to specify the configuration parameters for code pages for each system. Based on these configuration parameters, parameter the program knows that the source data is in a certain code page and it needs to translate that into the code page currently configured on the target machine. If the user enters the wrong code page configuration parameters, the transmitted data may get corrupted.

Dynamic Advanced Program-to-Program Communications Support for Different
Code Pages

      Connecting unlike systems is a major development activity and
different communication protocols such as APPC are developed for
transferring data between these unlike systems.  The code pages for
these systems are in most cases different and a data conversion is
needed from one code page to the other while transferring data.  The
current implementation requires the user to specify the configuration
parameters for code pages for each system.  Based on these
configuration parameters, parameter the program knows that the source
data is in a certain code page and it needs to translate that into
the code page currently configured on the target machine.  If the
user enters the wrong code page configuration parameters, the
transmitted data may get corrupted.

      This invention proposes a new elegant method to do the code
page conversion without asking the administrator to specify the
source and target code pages at configuration time.

      The source system at APPC initialization time queries the
target system to find out its configured code page.  Once the target
system receives the source machines "QUERY_CODEPAGE" request, the
target system then transmits its configured code page number back
(contained in the Header information of the reply packet) to the
source machine.  The source system then reads the code page
information from the header of the incoming reply packe...
