Product Description

Control/DCD is the latest version of the DCD Data Correlation and Document product. Control/DCD provides both online and batch capabilities. Control/DCD is the all-in-one product for managing both individual COBOL programs, JCL, Copybooks, as well as entire COBOL applications. Control/DCD uses ISPF’s Find Command to call Macros that do deep analysis on a COBOL program. This makes your average programmer more productive when making program fixes or changes. Control/DCD can reduce the Mean-Time-To-Repair from hours into minutes.
Managing a Legacy Modernization Project for Mainframe Applications has become a difficult task. The shortage of experienced mainframe talent has left organizations with little choice but to offshore or farm out the maintenance of Legacy Application code to programmers who probably have little knowledge of the application’s logic or its business rules.
Legacy Modernization Projects thrive on COBOL talent whether in the U.S. or offshore. The shortage of Mainframe z/OS talent becomes a serious threat to those organizations heavily invested in the Mainframe who are planning to rejuvenate code or move it to another platform.
There is an alternative way of addressing this problem.
Implement an Intelligent COBOL Code Analyzer into the Legacy Modernization Process.
Control/DCD is the latest in a line of major releases for the product, but the newest version incorporates many new features and capabilities that take advantage of COBOL V6.1 and z/OS 2.2. When implemented Control/DCD delivers the most advance COBOL Analytics and Documentation capability in Marble Computer’s 33-year history.

Control/DCD Digital Documentation Output

Control/DCD now offers the Digital Documentation Manual (DDM) as an alternative output format. The manual is created on the mainframe and transferred to the PC via FTP in one of three formats: .pdf, .doc, .txt. This manual is a complete English-like translation of the COBOL program usable by all parties in a DevOps environment.

Control/DCD How It Works

Control/DCD creates an ISPF documentation file, an Alternative Compile Listing (ACL) or the Digital Documentation Manual (DDM) for each program. A COBOL compile is not required to use Control/DCD’s capability.

Control/DCD Commands

Control/DCD creates a new powerful way to use the ISPF editor that makes it simple for the COBOL programmer to quickly understand the flow of the program as to data and process. Business rules are easily interpreted, data analysis is made simple, dead code is found and can be eliminated.
By utilizing Control/DCD’s simple command structure and operational command words programmers can issue an ISPF FIND for Macro functions.

Control/DCD Benefits

Adds an Intelligent COBOL Analytical capability to your Legacy Modernization Project.
Produces an actual COBOL Digital Documentation Manual in in .pdf format for transfer to a PC or a documentation library.
A simple command structure, with the addition of one character (An & character) added to the Find Command that works with a program’s data names, paragraph names, and more. Thus, the adoption rate is fast and efficient.
Control/DCD requires very little training.
Productivity is dramatically increased from the time the code is opened for remediation until it’s ready for Alpha and Beta Testing.
Management statistics are produced so that the final code changes can be analyzed as to the quality of the program. Project management is now able to deliver projects on time and under budget.
Better code means less Job Failures which creates better utilization of the production environment, makes life easier for Job Schedulers and those that support Job Scheduling systems.
