Creating a DBCS conversion dictionary
To create a DBCS conversion dictionary, do the following:
1. Use the Create DBCS Conversion Dictionary (CRTIGCDCT) command.
2. Name the dictionary, QUSRIGCDCT, so it can be used during DBCS
conversion. The system uses the dictionary if it is the first user-created
dictionary found when searching a user’s library list.
You might call the dictionary by another name while it is being created to
prevent application programs from using it for conversion. Later, change the
dictionary name using the Rename Object (RNMOBJ) command.
For example, to create a user DBCS conversion dictionary to be stored in the
library DBCSLIB, enter:
CRTIGCDCT IGCDCT(DBCSLIB/QUSRIGCDCT)
3. Use the EDTIGCDCT command to put entries and related words into the
dictionary after creating it. See “Editing a DBCS conversion dictionary” for
instructions on putting entries in the dictionary.
Editing a DBCS conversion dictionary
Use the Edit DBCS Conversion Dictionary (EDTIGCDCT) command to edit the
DBCS conversion dictionary. Use editing to add user-defined characters to the
dictionary, so that users can enter characters using DBCS conversion, and rearrange
terms in a DBCS conversion dictionary to suit individual needs.
Requirements for a DBCS conversion dictionary: The display station needed for
use while editing the DBCS conversion dictionary depends on the value that you
entered for the ENTRY parameter on the EDTIGCDCT command:
v If you specified a specific string with the ENTRY parameter or if you want to
display double-byte characters, you must use a DBCS display station.
v If you did not specify a specific string with the ENTRY parameter, or if you do
not want to display double-byte characters, use either a DBCS display station, or
a 24-row by 80-column alphanumeric display station.
DBCS conversion dictionary operations: You may perform the following editing
operations on a user-created DBCS conversion dictionary:
v Add entries to the dictionary (including adding the first entries to the dictionary
after it is created). The dictionary can contain as many as 99,999 entries.
v Delete entries from the dictionary.
v Change entries in the dictionary, such as replacing the DBCS words related to an
alphanumeric entry.
v Move the DBCS words related to an alphanumeric entry to rearrange the order
in which they appear during DBCS conversion.
The only editing function that you can perform with QSYSIGCDCT, the
system-supplied dictionary, is to move DBCS words related to an alphanumeric
entry. Move words in order to rearrange the order in which they appear during
DBCS conversion.
Displays used for editing a DBCS conversion dictionary: After you enter the
EDTIGCDCT command, the system presents either the Work With DBCS
Conversion Dictionary display or the Edit Related Words display, depending on
the value entered for the ENTRY parameter on the command.
