Utility Features
The ccnv utility provides features necessary to customize code conversion tables. These are described
below:
• Table customization: Customizes the specified code conversion table according to the user's cus-
tomization information (definition statements) specified by the user. The standard code conversion
table cannot be modified. This feature is also used for conversion of user-defined characters.
• Table information output: Outputs information on the code conversion table such as the type of
conversion, creation date, and date last modified.
• Table dump output: Outputs code conversion table dump results to a file. The contents of this dump
output only concerns the codes, and does not include internal information such as header inform-
ation contained in the code conversion table. The resulting file name is the code conversion table
name with “.dmp” appended to the end as the file extension.
• Standard table generation: Re-generates the standard code conversion table provided. Use this
feature when the standard code conversion table is modified or deleted unintentionally or by hard
disk failures.

customize the code conversion table.
