Additional Services

  • Supports all versions of PACBASE, all platforms, all databases.
  • 100% fully automated (Not 99, or 99.99, but 100%!)
  • Produces structured, readable and maintainable COBOL code
  • 100% functional equivalence guaranteed
  • Allows for multiple iterations to tune the result’s quality to the company’s specific requirements
  • Proven in use – this technology has already been applied to over 100 million lines of code;
  • Cost and quality – the level of automation allows for aggressive budgets and planning;
  • Independence – as the migrated application can be easily rehosted. It only relies on de facto standard components for which replacement products are available on different platforms (CICS, IMS, DB2, etc.);
  • Flexible process – without any freeze period during which maintenance must be suspended or duplicated;
  • Scientifically designed testing process – an order of magnitude more efficient than the more conventional approaches.


PACBASE’s technical merits are impeccable. It is an efficient and rigorous development environment that has proven its ability to master complexity and ongoing changes over the years.

Even so, using a proprietary environment to maintain mission-critical applications induces a dramatic risk, such as, when the – sole – vendor of the tool changes its focus, or decides to terminate the product altogether.

To best address this concern, Raincode’s PACBASE migration solution induces no dependency. At the end of the process, the application does not depend on any additional proprietary component or tool, be it Raincode’s or anyone else’s. It produces standard COBOL code that can be maintained using standard tools available in a vibrant marketplace.

Going to standard COBOL also opens a number of options including:

One can tap the COBOL market for more advanced needs than maintenance alone, to care for impact analysis, cross-referencing, quality control, etc.

COBOL consultants are far easier to find than PACBASE consultants, especially in an outsourcing context

COBOL systems can be rehosted to any target system, even if it relies on CICS or IMS/DC, as a wealth of emulation tools are available, thereby reducing the cost of ownership dramatically

The database can be migrated if needed, using one of the many specialized service providers in this area.

Code read and then generated by PACBASE is very redundant, as many artifacts result in code duplicated in hundreds or even thousands of programs. Centralizing these distributed components in copybooks reduces the amount of code to maintain, and thereby, reduces the cost of ownership almost linearly. The amount of code under maintenance can shrink by as much as 30%, in conjunction with the size reduction resulting from the code restructuring.

This centralization is performed by the clone detection process, which goes through the code, and identifies components that can be represented by plain COBOL copybooks, possibly with parameters.

Clone detection

In addition to clone detection, which applies to the entire portfolio after transformation, PACBASE macros and segments are dealt with specifically at the very beginning of the process.

Data structures referring to PACBASE segments, and code fragments expanded from PACBASE macros are recognized, and replaced by native COBOL copybooks as a preliminary phase, so that these components, which are so essential to the PACBASE way of designing systems are centralized in a recognizable fashion. This allows ongoing maintenance to keep a full trace between the original PACBASE artifact and the resulting COBOL code.

The transformations can be enabled or disabled one by one, together with additional parameters:
