Release 3.5: 07/28/99

Cobol Data File Reader technology

Cobol Data File Reader technology is introduced. It allows you to read and interpret Cobol data files (sometimes also called ISAM files). A number of specific converters from Cobol data files to non-Cobol data formats was built using this technology:

  • data2flat: Cobol Data File to Flat Data File converter. It converts Fujitsu Cobol and Micro Focus Cobol data files to flat text file format. Flat files can be easily loaded into Microsoft Excel and most modern databases. Download Evaluation Copy now!
  • data2cr: Data access DLL that is used by Seagate Software Crystal Reports to read Fujitsu Cobol data files.
The Cobol Data File Reader technology consists of the following infrastructure items:
  • cbl2fdd: Cobol File Descriptor Extractor. This programs parses Cobol program that can read or write a specific Cobol data file. It extracts File Descriptor information necessary to read this Cobol data file from SELECT and FD statements for the file and puts it into machine-readable FDD and RDD files. Download Evaluation Copy now!
  • DataAccess: DataAccess library takes the File Descriptor data stored in FDD and RDD files and it uses this data to read the actual Cobol data file. RDD and FDD files can be automatically generated by Cbl2Fdd or created manually.
You can license Cobol Data File Reader technology to add Cobol data file reading capability to your application.


  • Approximately 150 new functions and classes were added to CobolTransformer Toolkit API. These convenience functions make writing Cobol converters and analyzers a breeze. These additional functions were developed while building several large commercial Cobol converters and preprocessors.
    Download CobolTransformer Toolkit Evaluation Copy. It contains a new version of the CobolTransformer Toolkit manual.
  • A number of small bugs and memory leaks was fixed, so expect the latest versions of converters to run faster and take less memory.

Release 3.4: 04/18/99

Bug fix release 3.4.3 posted on 05/12/99.

Goal of this release is to make our tools more convenient on WIN32 systems (Windows 95, Windows 98, Windows NT).

Introduced new installer for WIN32 systems. It creates entries in Start Menu, automates deinstallation, and packages the whole distribution as one executable file.

Introduced CL-launch -- GUI tool that is used for launching command-line tools. It stores command-line tool ouput in scrollable window that can be printed and saved. Also CL-launcher memorizes history of the tool invocations.

Printable manual for Converters and Tools in PDF format.

Introduced shareware trial versions of CobolBeautifier and CobolReporter.

Release 3.3: 03/01/99


Like everybody else, we think that software reuse is important. We keep asking the question: after we wrote a lot of code for a code conversion project X, how can we reuse a bulk of this code in the upcoming project Y?

The question of reuse is so important for us that we decided to add transformations architecture to CobolTransformer Toolkit. We broke all our converters into a number of small transformations that have universal interface and run equally well in command-line and visual environments. Each transformation has a well-defined functionality and can be easily reused in other projects.

With transformations, developing a new conversion has become a much simpler process because less code has to be written: (1) take transformations written for previous projects and select ones that can be used in the new project, (2) add to them transformations from the Standard Transformation Library (STRL) that is a part of CobolTransformer, (3) write a few new transformations that are unique for your project, and that is it.

Transformation is an object that searches and/or transforms the Program Tree. Transformations follow certain conventions that allow CobolTransformer system to relieve a developer from many chores related to Program Tree transformation. In addition to reuse transformations bring us other important conveniences:

Command-Line and Visual Environments
The same transformation can be run both from command-line (batch) environment and from visual (GUI) environment with no code changed in the transformation itself. So it is like in Java, but on a bigger scale: Write Once, Run Everywhere, where Everywhere spans command-line and visual world on multiple platforms!

Transformation objects may contain configuration parameters (options). Each configuration parameter may have an option descriptor associated with it. This option descriptor tells the system how this parameter is set by end user both from command-line environments (argc, argv arguments) and from visual environments (tabbed dialogues in WIN32 GUI).

Inheritance by Specialization
If you take a transformation with configuration parameters and specialize it by setting its configuration parameters, the resulting transformation can be given a separate name and treated just like transformation.

Save and Load
Transformation instances (specialized transformations) can be saved to file and loaded from file.

Logging and Debugging
CobolTransformer system can automatically generate a log that lists all transformations applied to the Cobol program. A number of debugging features is implemented too.

Transformation Library

Often used transformations are assembled into libraries that from now on will be sold together with CobolTransformer, so that our customers may base their conversion effort on a solid foundation of previously written transformations.

Library of existing transformations helps you to start writing transformations for your conversion sooner, because:

  • You can reuse the library transformations directly, by incorporating them into your conversions.
  • The source for the library transformations is available, so you can reuse programming tricks from the library transformations.
  • Library transformation source provides a good example of how to write transformations, so that you learn faster by example.

Currently the following transformation libraries are available:

  • Standard Transformations that perform code normalization by bringing it closer to ANSI-85 standard. Includes name renumbering transformations used in cbl-beau.
  • SQL host variable normalization transformations.
  • Year 2000 windowing transformations.
  • IBM Cobol to Fujitsu Cobol transformations.
  • Micro Focus Cobol to Fujitsu Cobol transformations.

CobolTransformer manual contains a complete list of available transformations.

Object Configuration

In large programming projects we are dealing with objects that need to be configurable by user. For instance, in CobolTransformer we have Parser object, PrettyPrinter object and transformation objects that all have configuration parameters, such as dialect of Cobol to be parsed (in Parser) or indentation step (in PrettyPrinter).

We invented a template-based mechanism for describing configuration parameters that allows:

Command-Line and Visual Configuration
Configuration parameters, once described in our framework, can be configured by user both in command-line and visual (GUI) environments.

Readable Parameter files
Configuration parameters can be saved to text file in the form name = value and loaded from file.

Parameter Marshalling
Configuration parameter blocks can be sent across the network in platform-independent name = value format.

SQL parser

We added a parser and Program Tree for SQL/92 language embedded into Cobol program.

Preprocessor Integration

PrettyPrinter can now generate Cobol code containing '#FILE/#LINE' preprocessor statements that connect generated Cobol code to the original (before conversion) Cobol code.

One can use this feature to build a Cobol preprocessor that converts Cobol dialect A to Cobol dialect B and adds '#FILE/#LINE' preprocessor statements that let the compiler of dialect B to know where the code came from in dialect A so that debugging and error diagnostics happen in terms of original source. This effectively allows Cobol dialect B vendor to claim that they support dialect A without actually changing their compiler.

Speed Improvements

Code converters built with CobolTransformer are fast enough to be used as preprocessors for production compilers: 100-150 lines/sec for mf2fsc running on consumer-grade 166Mhz Pentium PC.

Evaluation Version Limits Increased

By popular demand, CobolTransformer Evaluation Package limits were increased to:
  • 1024 lines per source file (was 256),
  • 1024 lines of code total (was 256),
  • 512 names in a program (was 128).

Release 3.2: 12/15/98

CobolGrep and Query Language

We invented CobolGrep and Query Language (QL) used in CobolGrep so that Cobol developer can perform program searches such as "Show me all the lines of code that contain data item declarations that have VALUE clause and belong to LINKAGE SECTION or FILE SECTION".

Query Language is used to formulate search criteria that work on Cobol Program Tree that represents a Cobol Program in question.

The above search looks as follows in QL:


It means: "Find a node in Cobol Program Tree such that this node is data item declaration and this node is a descendant of Working-Storage Section node or of Linkage Section node and this node has Value Clause node".

Data Item Length & Offset computation

Now for every data item we compute:

  • its length,
  • its offset from 01 level start,
  • its offset from the surrounding section start.
This data is necessary for figuring out data item aliasing information. Developed CobolReporter tool that reports lengths and offsets of every data item. It also generates a lot of other useful information about your Cobol program.


  • Performed usability analysis of command line tools and reworked the set of available command line options. Allow multiple files in converters.
  • Use Kenonic Controls CrypKey License Manager software to enforce CobolTransformer licensing agreements.
  • Converted CobolTransformer manual to Adobe PDF format.
  • Implemented Micro Focus $IF/$ELSE/$ENDIF/$SET preprocessor directives to further enhance MF Cobol parser.

Release 3.1: 08/09/98


The most important feature of 3.1. is revolutionary SourcePrint capability that allows you to fully restore the unchanged parts of the Cobol program, while using the full power of the tree-based program transformation engine.

Details. Our general sequence of steps needed to perform a program transformation is fairly standard: (1) parse the program making it a Program Tree, (2) transform the Program Tree, and (3) generate the converted Cobol code from the transformed Program Tree.

The only problem with this approach is that the Cobol code generated from the Program Tree usually differs from the original source code. The differences are minor -- words appear in different columns, some optional words may be skipped or added.

These differences are result of a process of automatic code generation which cannot exactly reproduce the original program. While these differences may seem insignificant, they do not allow to use diff or any other automatic file comparison utility to independently verify what lines were changed by the converter. This is because the little differences introduced by beautification make every line look different to these diff utilities.

Enters the SourcePrint. We store additional data in the tree nodes. This data allows us to generate Cobol code that does not differ from the original code -- down to a single byte -- for the tree fragments that were not changed by transformations.

Code that is generated from the new tree nodes is generated in the beautified mode as was the case in the SCT versions prior to 3.1.

What does it mean for you? It means that Cobol converters that use SourcePrint are easily and inexpensively verifiable. That is, upon finishing the conversion, you can run line diff utility that compares original directory with the full source of your application to the directory with the converted source. The generated difference logs are guaranteed to be minimal and reflect only changes made by the converter (and not the changes introduced by beautification or other parsing/printing side effects).

Copybook Generation

The other important feature of the Version 3.1 is its ability to fully control the copybook structure generation.

As you may already know, a Cobol program consists of the main file and copy library (or copy book) files that are included in the main program by a preprocessor. Cobol parser needs to inline all the copybooks in order to correctly parse the program and build the complete Program Tree.

However, when it comes to code generation, the almost universal desire of the conversion engineers is to have their copybook structure back. That is, the converted main file must contain COPY statements that refer to the converted copybooks.

Since the copybooks also may be affected by a conversion, this creates a non-trivial problem of un-inlining the copybooks. By un-inlining we mean process of code generation in which a main program with COPY statements and series of copybooks used by these statements is generated from a single Program Tree.

The correct and fully functioning implementation of copybook un-inlining is the new feature available in CobolTransformer 3.1.

In addition to restoring the original copybook structure you can easily change the layout of copybooks: fully inline the existing copybooks, separate a fragment of code into a new copybook, or generate a totally new hierarchy of copybooks. All this is made possible by storing the copybook-related information on the Program Tree.


Another big advance in CobolTransformer is Client-Server Packaging. This is in addition to the previously standard Library Packaging.

In client-server packaging all non-trivial functions such as parsing and pretty-printing occur in CobolTransformer server executables that run in a process/task that is separate from the process/task of your converter.

The thin CobolTransformer client linked in with your conversion application contains only the tree transformation functions and proxy functions for parsing and pretty-printing that call the CobolTransformer server.

Client-Server Packaging makes CobolTransformer a bit slower, because some time is spent on Program Tree externalization and internalization. However, it provides numerous advantages that are well worth the price:

  • It is possible to have CobolTransformer client library in different languages. In addition to C++, client libraries in C, Perl and Cobol are planned.
  • Memory allocation problems such as leaks and dangling pointers cannot possibly propagate from your application to CobolTransformer and back, because your application and CobolTransformer run in separate address spaces.
  • We are able to provide you with a Free Trial Copy of CobolTransformer. It was not possible when CobolTransformer was a static library.

The Library Packaging of SCT is still available.

Free Evaluation Package

Now, with introduction of Client-Server Packaging you can Try CobolTransformer For Free.

Yes, you can actually write your own conversion/analysis application that uses CobolTransformer and see how it works on small (less than 256 lines) programs.

Once you are satisfied with the results, you can purchase a CobolTransformer license and the application that you wrote will then work on program of any size. This is a new risk free way to appreciate the power and flexibility of CobolTransformer.

Release 2.1.2: 02/17/98

* Introduced Symbol Table, Use-to-Definition and 
Definition-to-Use links for Named Objects.
Now for every User-Defined Word (Name) we compute
a list of all Definitions for this Name.
For every Use of a Named Object we have a link to 
the Definition of this Named Object, and for 
every Definition of a Named Object we have a list of 
links to all Uses of this Named Object.
This greatly simplifies programming of renaming
and other symbol table-related conversions in
We have introduced function that performs renaming
of Named Objects Definition and all its Uses.
For every definition CobolTransformer can compute
Fully Qualified Name and Shortest Unique Qualified
These new functionality is demonstrated in the new
Paragraph/Section/Data-Name Renumbering tool,
that is a part of cbl-beau.
If we consider Use-Definition links together with
Parent-Child links, Program Tree effectively
becomes a general-case Graph that has a Tree
skeleton. We introduce a technology that makes
flattening/unflattening of these general-case
Graphs possible.
* Released free Paragraph/Section/Data-Name Renumbering
tool as a part of CobolBeautifier cbl-beau to demonstrate
our Def-Use links capabilities.
The tool correctly handles name collisions and computes
Shortest Qualified Name that uniquely identifies renamed
Named Object.
* Parsing.
- Return the parsed contents of the whole source file
as a single Expression Tree. In previous version
we were calling user-defined processing function and
passing fragments of the whole tree to it.
The processing function options was left intact in
2.1.1 for compatibility with old SCT version and
for processing very large Cobol programs, but this
option is not a default choice.
- Added Wang Cobol dialect construct to parser and 
code generator.
- Added parsing and code generation for Fujitsu NetCobol.
To be available through Fujitsu distribution channels.
- Build a Tree of Nested Programs (ANSI-85) when
they are present.
- Insert special Error Nodes into the Program Tree
when syntax error occurs while parsing, so that
erroneous statements do not just disappear from
the output file, but can be represented there with
a noticeable text such as [SYNTAX ERROR].
- Allow user specify her own Warning/Error/SevereError
processing functions.
* Cobol Code Generation.
- After PrettyPrint() has generated Cobol code 
for a given expression tree, every node in this tree
knows its position in the generated text.
- Added API to generate tagging text in columns 73-80
of the output line. This text contains one increasing
Line Counter, for which starting value and step can be 
- User-Defined Primary Table and System-Defined
Default Table are now automatically merged into
one Code Generation Table that has constant access
time.  User can still specify a separate Primary
Table, but when PrettyPrint() is called first
time, the merge process occurs.
* Native makefile for WIN32.
WIN32 customers will receive a native WIN32 makefile
that works with Microsoft make program called "nmake".

Older Releases

12/02/97: Version 1.4.1
* Implemented conditional compilation commands 
%define, %ifdef, %endif, %include in BtYacc.
BtYacc is a parser generator used in CobolTransformer.
This change allows us to break the Cobol grammar into
several files/modules that can be assembled for shipping
according to the individual customer desires.
The first feature separated into add-on module is 
DMS/80 and DMS/1100 Data Manipulation Language (DML)
implemented in ver. 1.4.0.
10/26/97: Version 1.4.0
* In addition to "Cobol Language Dialect" lexer option 
-language=dialect created "Embedded DB Language Dialect" 
option -db=dialect.
We separated language and DB dialect options so that 
language dialect option and DB dialect option 
can be changed independent of each other.
Currently only DMS/80 DML and DMS/1100 DML is implemented
as Embedded DB Language Dialect. We plan to add
CA-IDMS as another Embedded DB Language Dialect.
* Now CobolTransformer can parse and synthesize 
DMS/80 and DMS/1100 Data Manipulation Language (DML).
This is Embedded Database Manipulation language for
a UNISYS network model database built to CODASYL spec.
Use -db=dml option in cbl-beau to allow DML in the program.
08/21/97: Version 1.3.1
* Major redesign for the CobolTransformer Web site 
* Implement NOTE statement (OSVS).
This statement is yet another way to have comments in
Procedure Division.  Fix several bugs in OSVS dialect
08/10/97: Version 1.3
* Create mf2fsc -- prototype of MicroFocus Cobol to Fujitsu
Cobol converter.  Make this prototype freely available for
download.  We expect this prototype to evolve into a
finished product in the near future.
* Considerably enhance expression tree handling functions.
Introduce tree walker function, PICTURE character-string
SECTION clauses tree representation.
* Make separation between CobolTransformer library code and
CobolTransformer user code more explicit and formal.
Require that user code and CobolTransformer code reside
in different directories. Tune makefiles to handle this
05/16/97: Version 1.2
* Completed implementation of full ANSI-85 and MF Cobol
syntax.  Specifically, implemented COMMUNICATION SECTION
* Passed CCVS -- Federal Cobol Compiler test suite by
National Institute of Standards and Technology
(NIST). Fixed a number of bugs in lexer and parser to
achieve this.  Note: CobolTransformer was not formally
submitted to NIST for testing, because it is not a *full*
compiler. But we made sure that all the Cobol sources in
CCVS are parsed and beautified correctly.
* Ported CobolTransformer and cbl-beau to SUNOS 4.1 (UNIX)
platform.  The Cbl-Beau executable also runs on Solaris 2.5.
* Allow separators not to be finished with spaces when
-lang=mf is on.  MicroFocus compiler allows constructs like
"AAA>=12" be understood as "AAA >= 12".  According to the
standard, though, "AAA>=12" is a single character-string,
not 3 character-strings, because '>' and '=' by itself are
not separators and therefore space separator is required
between "A" and ">=" and between ">=" and "12".
CobolTransformer now can parse constructs like this
according to MF rules.
* Added -gen-max-indent=NNN option. Sets maximum allowable
indentation to column NNN.  If your program has too many
levels of statements and/or gen-indent-step is large, then
you can use this option to stop indentation at a specified
03/01/97: Version 1.1
* Native compiler (Visual C++ 4.1) support for WIN32 (MS
Windows 95 and NT).  In version 1.0 we used CygWIN32
GCC-2.7.2 compiler to compile cbl-beau.  As a result,
run-time library CYGWIN.DLL was required to run cbl-beau.
In version 1.1 we switch to Visual C++ version 4.0
compiler.  It builds native WIN32 executables that do not
require any extra DLLs to run.  Also it produces executable
that has a much better processing of CTRL-C signal.
* Support for Ryan McFarland COBOL-85 was added.  Only
RM/COBOL-74 was supported at CobolTransformer version 1.0.
* Cobol generator now generates code that strictly follows
all Area A/B rules.  Cobol Reference Format standard
prohibits some language elements (SELECT clause, etc.) from
appearing in Area A, they can only start in Area B.  In
version 1.0 some of Area A/B rules were disregarded.
02/01/97: Version 1.0
* First publicly available release of CobolTransformer.
* Created CobolTransformer Web site at
