Base VM TCP/IP Support for the EuroNearly 200 new translation tables (TCPXLBIN files) have been added to VM TCP/IP. All of the tables have a file name of the form hhhhwwww, where hhhh is the 4-digit decimal code page number to be used on the host, and wwww is the 4-digit decimal code page number to be used on the client. Use leading zeroes if necessary.
For example, assume that you are using host code page 1047 (POSIX) and workstation code page 819 (ISO 8859-1). The file name would be 10470819
The code page you choose depends on the assumptions made by the various operating system and application environments. For example, even though you are using a Windows operating system, you may have a file that was copied from a Unix system that requires a Unix-specific code page.
The default translation table for all VM TCP/IP clients and servers is STANDARD TCPXLBIN. This is a 7-bit ASCII non-reversible translation. All extended ASCII characters with values greater than 0x7F are lost because the high-order bit of each octet (byte) is ignored. All other translation tables included with VM TCP/IP are 8-bit tables.
The 8-bit tables provide the highest fidelity of transmitted data, but should not be used in situations where a client or server is known to treat the high-order bit in each octet as a parity bit.
It is important to recognize that changing a default translation table for servers such as FTP and NFS can corrupt data in a file if that file is uploaded and downloaded using different translation tables. (This does not apply to binary transfers, of course.)
Translations are provided for all standard country code pages and their euro equivalents, code page 924 (ISO 8859-15, EBCDIC), and code page 1047 (IBM OpenExtensions) to the following workstation code pages:
- 819 ISO 8859-1 (ASCII)
- 923 ISO 8859-15 (ASCII)
- 850 PC
- 858 Euro-ready PC
- 500 International EBCDIC
- 1148 International euro-ready EBCDIC
- 1047 IBM OpenExtensions EBCDIC
- 1252 Microsoft® Windows®
In addition, code pages are available to convert between each standard country code page and its euro-ready equivalent.
