The character code converter can convert character codes covered in CommuniNet.

When using the converter, issue and call functions in the following order.

1. Start of character code conversion
   dc_clt_codeconv_open()
   
2. Execution of character code conversion (Conversion can be executed two or more times)
   dc_clt_codeconv_exec()
   
3. Termination of character code conversion
   dc_clt_codeconv_close()
   

Once character code conversion is started (dc_clt_codeconv_open()), you can execute character code conversion (dc_clt_codeconv_exec()) two or more times until you terminate the conversion (dc_clt_codeconv_close()).

• The use of this converter requires a CommuniNet code mapping table. Use the CommuniNet code mapping utility to create a code mapping table, then use the converter.
• You cannot use a code mapping table unless you first save the table using the CommuniNet code mapping utility after the installation of CommuniNet. Before using the converter, use the CommuniNet code mapping utility to save a code mapping table.
• The filename of a CommuniNet code mapping table must be CMAPEX.TBL. Before using the converter, store the code mapping table under a Windows directory.
• The processing by the character code converter does not reflect any changes made in a code mapping table by the CommuniNet code mapping utility during processing.
• You cannot save error logs and UAP trace information for the character code convert.
• Issue the function for starting character code conversion (dc_clt_codeconv_open() or CBLDCUTL('CNVOPN ')) only once and then execute character code conversion (dc_clt_codeconv_exec() or CBLDCUTL('CNVEXEC ')). Do not issue the function for starting character code conversion more than once to prevent memory shortage. If you issue two or more functions, issue one function for terminating character code conversion (dc_clt_codeconv_close() or CBLDCUTL('CNVCLS ') for each of the issued functions.
