Marble Computer Takes On All Perplexing Challenges

Application modernization is a fact of life for most IT organizations and any software company. The use of new computing platforms such as the Cloud as well as new mobile computing devices has created challenges far beyond one could ever imagine a few years ago. However, these Legacy Applications contain the mission-critical data processes of past generations. The key to success is to unearth these secrets and accurately upgrade these Legacy Applications or move them to new platforms as required. At Marble Computer, we have the software products to make this task easier.

A History of Our Clientele

Marble Computer has a long history of supporting enterprise computing clients that date back to 1976. Marble Computer delivers best-of-breed software tools for IBM mainframe customers to ensure the integrity, performance and analysis of their COBOL applications. Our flagship product, Control/DCD, documents COBOL programs with our Digital Document Manual (DDM) technology.  Docet/EV documents the IT Enterprise. Marble Computer’s software tools focus on Dev/Ops, Legacy Modernization and Cloud Migration projects.

The Tools We Incorporate Into Our
Software Applications

Control/DCD is the latest version of the DCD (Data Correlation and Document) product. Control/DCD significantly reduces the cost of maintaining COBOL applications and produces the Digital Documentation Manual (DDM).
Control/DCD has the necessary functionality to provide warnings and capture errors in older versions of IBM compilers. There are many types of errors that the Control/DCD pre-compiler will catch thus making migrations to enterprise COBOL compilers faster and less costly.
RES is an advanced set of software products for documenting the IT Enterprise. Docet/EV is a must-have tool for Legacy Modernization, DevOps and Cloud Migration implementations.
