Abstract: The present invention is a multi-layer computer architecture which separately extracts ALC business and logical functions and data. The architecture creates a Java object model or other target language object model which allows comparison of ALC data with target language data to verify logical processes. These object models can be directly traced back to the legacy ALC. The data model is automatically generated from a scan of the ALC and leverages generic patterns which can be reused to generate Java representations of other legacy code bases.

Abstract: The present invention is a TRL Engine based validation methodology which also allows validation at any level of granularity required from the application/run level all the way down to the individual line of code, which is utilized for unit testing as well as system testing.

Abstract: The method for translation of assembler computer language to validated object-oriented programming language converts Assembler Language Code (ALC) logical processes to equivalent object-oriented processes. The method uses various iteratively updated rules sets and graphical analysis tools to automate the translation process. The method further uses a Technical Rule Language (TRL) as an intermediate scripting language to map ALC sequential instruction sets to simplified Java constructs, which are verified and then translated to Java executable code.
