Japanese DBCS conversion

DBCS conversion is intended for Japanese character sets and its use is limited for application to other double-byte character sets.

When you use DBCS displays to enter double-byte data, you can use the various data entry methods supported on the display, or you may choose to use the i5/OS™ DBCS conversion support. DBCS conversion lets you enter an alphanumeric entry or DBCS code and convert the entry or code to its related DBCS word.

Specifically, DBCS conversion lets you convert the following characters:

A string of alphanumeric characters to a DBCS word
English alphanumeric characters to double-byte alphanumeric characters
Alphanumeric Katakana to double-byte Hiragana and Katakana letters
A DBCS code to its corresponding double-byte character
A DBCS number to its corresponding double-byte character

Japanese system-supplied dictionary

The QSYSIGCDCT is the system-supplied dictionary that is stored in the library, QSYS. It is a collection of entries with a Japanese pronunciation, expressed in alphanumeric characters, and the DBCS words related to those entries. The system checks this dictionary second when performing DBCS conversion.

QSYSIGCDCT contains these entries:

Personal names
- Family names
- First names
Organization names
- Private enterprises registered in the security market
- Public corporations
- Typical organizations in the central and local governments
- Most universities and colleges
Addresses
- Public administration units within the prefectures
- Towns and streets in 11 major cities
Business terms, such as department names and position titles commonly used in enterprises
Individual double-byte characters, including basic double-byte characters, as defined by IBM^®

You cannot add or delete entries from this dictionary. However, you may rearrange the related DBCS words so that the words used most frequently are displayed first during DBCS conversion.
