Abstract: The present invention provides a system and process which has the advantages of shortening the time and cost required to create a new localized version of a software product by automating much of the language translation process; by providing tools to automate the modifications to the program being localized, thereby reducing the probability of creating errors in the localization process and providing some measure of consistency between subsequently localized new releases of the product, and between different locales. The system disclosed includes an environment and tools to develop software modules to create methods to display, enter or print various single and multi-byte character sets. Moreover the system disclosed provides a mechanism for an independent software developer to localize a software product, using only a binary copy of the target program and the localization tool kit for that product.
