National Language Support

Implementing NLS | CONVXLAT Utility

VM:Webgateway national language support (NLS) allows data centers to serve data in a character set for a language other than U.S. English. NLS also enables CGI programs to translate data between its EBCDIC and ASCII representation.

For example, a French firm might have a report that is written in the French language. The French languages uses a set of characters. Using the VM:Webgateway NLS capability, the firm can serve the EBCDIC file and have it displayed on web browser that is configured to display characters in the French ASCII character set.

IBM's TCP/IP for VM supplies several translation tables (code pages). The following chart identifies the languages and translation tables that VM:Webgateway supports:

Language		Translation Table's CMS Filename and Filetype
Austrian German		AUSGER TCPXLBIN
Canadian French		FRENCH TCPXLBIN
Danish		DANNOR TCPXLBIN
English (U.K.)		UK TCPXLBIN
English (U.S.)		*
Finnish		FINSWED TCPXLBIN
French		FRENCH TCPXLBIN
German		AUSGER TCPXLBIN
Norwegian		DANNOR TCPXLBIN
Swedish		FINSWED TCPXLBIN
* The U.S. English translation table, USENGLISH, is built into VM:Webgateway and is always present.

At system startup, VM:Webgateway searches all accessed filemodes in standard CMS search order and loads any TCPXLBIN files it finds. To see what tables your VM:Webgateway SVM has loaded, refer to the Translation Table Summary.

Note: The languages that VM:Webgateway supports are independent of the server's CMS language setting.

Implementing National Language Support

Use the CONFIG FILETYPE command to associate a particular type of character set translation with a particular CMS filetype that VM:Webgateway will serve. For example, you might define a filetype called HTMLGER using the TRANSLATE AUSGER option. VM:Webgateway, when serving a file of type HTMLGER, will translate the file's German EBCDIC representation to the equivalent German ASCII representation.

Use the CGI READ, CGI URLDECODE, and CGI WRITE commands to take advantage of NLS when reading or writing data with CGI programs.

Users who want to read files or use CGI programs that your web server serves must set their web browser to display text in a coded character set that contains the characters used by the language in which the data is sent. In the example above, a web browser user who wants to read a file of type HTMLGER must set his or her web browser to use a character set that contains the characters in the German language.

Using the CONVXLAT Utility to Modify Translation Tables

Under the following circumstances you must use IBM's TCP/IP CONVXLAT utility:

You modified the source representation of one of IBM's translation tables
You built your own translation table and need to convert it to its binary representation
You want to use a translation table for which IBM shipped only the source

For instructions about using the CONVXLAT utility, refer to IBM documentation on planning and customizing.
