Dictionary Manager

Dictionary Manager helps to translate the default product strings as well as user TDL strings into any language. The application allows translation of strings used in the default product, and customisation the TDLs into the selected language. It creates a final dictionary file .DCT , to distribute it along with the product, and the TCP.

The dictionary files can be secured by providing authentication details. The process of securing the .DCT file is similar to TCP compilation.

Dictionary Manager can be launched from the Tools menu.

Note : Refer to the section Dictionary Manager for the detailed explanation of dictionary manager functionality.
