v When you have copied a version of the master table to a data file and you now<br />

want to restore that version.<br />

You should always migrate or copy the Japanese DBCS master sort table<br />

together with the Japanese DBCS font tables.<br />

How to copy the Japanese DBCS master sort table from a data<br />

file<br />

To copy the Japanese DBCS master sort table from a data file, do the following:<br />

1. Enter the CPYIGCSRT command as follows:<br />

a. Choose the value OPTION(*IN).<br />

b. Use the FILE parameter to specify the name of the data file that contains a<br />

migrated System/36 or AS/Entry master file or an AS/400 master table<br />

previously copied to the file using OPTION(*OUT) with the CPYIGCSRT<br />

command. To migrate your System/36 or AS/Entry master file without<br />

using the System/36 Migration Planning book, use the TRANSFER command<br />

with the IFORMAT parameter on the System/36 or AS/Entry to save the<br />

#KAMAST master file on diskette. Use the AS/400 Copy <strong>File</strong> (CPYF)<br />

command to copy the master file #KAMAST from diskette. Use the<br />

CPYIGCSRT command as described here to copy data from the file to the<br />

AS/400 Japanese DBCS master sort table.<br />

c. Use the MBR parameter to specify the name of the data file member from<br />

which you want to copy the master table data.<br />

2. Press the Enter key. Even though the information in the existing Japanese DBCS<br />

master sort table is overridden, that table must exist before you can use this<br />

command.<br />

3. To update the Japanese DBCS active table to reflect the new copied information,<br />

use the SRTXBLD procedure in the System/36 or AS/Entry environment, or the<br />

STRCGU command specifying OPTION(5). This must be done before you can<br />

use the sort utility to sort Japanese double-byte characters.<br />

Deleting a DBCS sort table<br />

Use the DLTIGCSRT command to delete a DBCS sort table from the system.<br />

When to delete a DBCS sort table<br />

Delete an unused DBCS sort table to free disk space, but you should always first<br />

save a copy of the table using the SAVOBJ command. You should delete the DBCS<br />

master sort table for a DBCS language if any of the following are true:<br />

1. You will not be creating any new characters for that language using the<br />

character generator utility.<br />

2. You will not be using the sort utility to sort characters for that language.<br />

You should delete the DBCS active sort table for a DBCS language if you will not<br />

be using the sort utility to sort characters for that language. The DBCS active sort<br />

table must be on the system to use the sort utility for this language.<br />
