How DBCS Conversion works
DBCS conversion is an interactive function between you and the system in which
you enter an alphanumeric entry. The system displays related DBCS words, and
you choose which word to use.
The system determines which words are related to an alphanumeric entry by
checking DBCS conversion dictionaries. The system checks two DBCS conversion
dictionaries when performing DBCS conversion. It checks the first user-created
dictionary named QUSRIGCDCT found when searching a user’s library list. Then,
it checks the system-supplied dictionary, QSYSIGCDCT, stored in the library QSYS.
(QSYSIGCDCT contains only Japanese double-byte characters.) You can create
other user dictionaries, and you can give them names other than QUSRIGCDCT,
but the system only refers to the first user-created dictionary named QUSRIGCDCT
found in your library list when performing DBCS conversion.
After checking the dictionaries, the system displays words related to the
alphanumeric entry. You then position the cursor under the word of your choice,
and press the Enter key. The system enters that word where the cursor was
positioned when you began DBCS conversion.
Using DBCS Conversion
You can change the user-defined dictionary used during DBCS conversion. Before
you change the user-defined dictionary, end your application program or end the
command that the system is performing. Then change the dictionary that is used
by changing the library list (using the CHGLIBL command).
You can create your own DBCS conversion dictionary for DBCS conversion. The
system-supplied dictionary is a collection of entries with a Japanese pronunciation
expressed in alphanumeric characters and Japanese DBCS words related to the
entry. See “Creating a DBCS conversion dictionary” on page 223 for instructions on
this procedure.
If no user-created dictionary is found, the system refers only to QSYSIGCDCT. See
“DBCS conversion dictionaries” on page 221 for more information on creating and
using DBCS conversion dictionaries.
Performing DBCS Conversion
The following procedure describes how to convert one alphanumeric entry to its
related DBCS word using DBCS conversion. You must start DBCS conversion
separately for each field in which you want to enter double-byte data.
Note: DBCS conversion is intended for Japanese data entry. Its use with other
languages is limited.
While performing DBCS conversion, you can display information about the
function by pressing the Help key. Help is available until you end DBCS
conversion.
