Promula Tools
Over the years, we have developed a number of commercial tools in the areas of computer language translation, software migration and multi-dimensional data management and modeling:
  1. gmBasic, the Great Migrations Visual Basic to .NET Migration Tool
  2. promulaFortran, the Promula FORTRAN to C Translator
  3. promulaADS, the Promula Application Development System
   gmBasic, the Great Migrations Visual Basic to .NET Migration Tool
This tool is designed to support the migration of Visual Basic Applications to .NET via translation to C# or VB.NET. It is a key component of our tool-assisted migration methodology. We use this tool to develop custom translation and refactoring solutions for our clients' migration projects -- large or small. For example, we employed this tool with great success in the BMW Financial Services "Visual Basic Retirement" Project. The purpose of this project was to migrate to .NET their entire enterprise portfolio of about 500 financial applications (totaling more than one million lines of VB6 code) via automated translation and refactoring of VB6/COM to C#/.NET. See BMW Financial Services .NET Adoption Case Study

gmBasic is a highly configurable, robust VB6/ASP/COM compiler that produces .NET source code output:
  • Compiler: Builds a comprehensive semantic model of the codebase implementation.
  • Analyzer: evaluates and restructures the model to fit the desired architecture patterns.
  • Author: processes the optimized model to generate clean, correct code that meets custom standards and conventions.

The hallmark features of gmBasic include the following:
  • Accurate - correctly transforms your application codebase to logically equivalent .NET code

  • Flexible - can be configured to produce translations that meet your custom restructuring and coding conventions; for example replacing COM components with managed components (eg, ADODB to ADO.NET)

  • Scalable - handles multiple related projects (combinations of VB6 components and ASP pages) as a single, logical migration unit, not just a batch of separate translation. The results is a coherent, consistent target codebase with no interop between migrated components.

  • Extensible - can be easily extended to recognize additional libraries or restructuring rules. We have an extensive XML-based migration configuration and a migration API.

  • Choice of Language - supports translation to both C# and VB.NET. This also applies to conversion of VBScript in your ASP pages to C# or VB.NET code behind.

  • Complete - supports all common VB6/ASP language features and COM components distributed with VB and Windows

  • Mature - based on proven principles of compiler design and extensive experience in large scale migration projects.

  • Fast - can translate typical VB projects in a few seconds (e.g., it takes 12 minutes to translate a huge codebase of 175 VBPs, 3000 files, and 1.8 million lines of code).

The best way to learn about gmBasic is to see it for yourself in the context of your application. Contact us to request a demo or to find out about our free migration assessment services.

   promulaFortran, the Promula FORTRAN to C Translator
First published in 1987, this tool is the best-of-breed FORTRAN to C translator around -- according to independent reviews.
This tool can be used to produce custom C translations that are both correct (functionally equivalent to the original FORTRAN) and C-readable (i.e., of high C-code quality, subject to the client's C programming standards or custom preferences).
Over the past thirty years, we have applied this tool in several hundred migration projects around the world and have helped our clients in the porting of their legacy applications (millions of lines of third-generation code) from mainframes and other proprietary systems to more contemporary, open platforms.
This tool is also a general-purpose, multi-dialect and portable FORTRAN compiler. It runs on multiple platforms and supports both the ANSI FORTRAN 66 and ANSI FORTRAN 77 standard dialects. It also supports a large number of common extensions such as those found in several commercial compilers, such as VAX FORTRAN, PDP FORTRAN, and PRIME FORTRAN.
Validated by the GSA FORTRAN Compiler Validation Test Suite, the Promula FORTRAN compiler works by compiling FORTRAN source code to compilable C source code (from where it derives its portability). It requires a C compiler to produce executable code and is the ideal processor for hybrid FORTRAN/C applications.

   promulaADS, the Promula Application Development System
promulaADS is an integrated program-development tool that encompasses a fourth generation language and a unique array database management system. It is designed specifically to increase programming productivity in modeling and simulations applications development and has been used as the host system in a number of large-scale modeling projects -particularly in the areas of energy, the environment, engineering and economics.
