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.

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.
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.
