Open Source COBOL Software

OpenFileAid is aimed to help people working with COBOL Copybooks and flat files, such as the orginal IBM FileAid. It allows to parse and load CopyBooks, to map the content of flat files to the fields of CopyBooks, to Intitialize CopyBooks...

RES is a pure Java based Open Source Cobol to Java translator. It creates maintainable Java code for a subset of VS Cobol syntax. It has been developed with JDK, JTB and Javacc.

This repository is for personal Cobol projects. The projects are stored here in the event someone needs to look at Cobol code for any reason. Most, if not all, of the code was created for personal projects and not professional use. Nevertheless, if the code is useful, feel free to download a copy and use in your own projects.

One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a Screen Painter, as some tools may call it) which allows the user to create screen layouts (which includes the use of colors) with delimited fields and respective input masks, and finally generate the SCREEN SECTION code that reflects that layout. All of it automatically - no code needed. The idea came from a program I used to use named EDITEL. I have adapted the concept (it was originally built for BLIS COBOL systems) and created a version that does this for GnuCOBOL and Microfocus COBOL. Enjoy !

PL1DOC is a documentation tool for PL1 projects entirely written in Java. It currently supports PL1 version 2.3 (later releases will be captured in the future). PL1DOC produces HTML output and provides a tagset to allow a rich annotation of source files.

The Universal COBOL Compiler (UCC) is a Java-based COBOL to Java bytecode cross-compiler. It's made up of a COBOL compiler, a Java-based COBOL runtime, and a package for manipulating Java class files.

This is the GUI version of Gary Cuttler's OCiC dos version. His was written in OpenCOBOL. This is written in MONO C# with GTK#. I give all credit to Gary for his originality.
