    We are doing amazing things with GnuCOBOL, it is an awesome product if you don't use it sorry! your loss. We migrated our application and we are developing with GnuCOBOL and i can assure you we have never had any problem.

    Installed 2.0 RC1 on Windows using Visual Studio Community, took all of 10 minutes to set up the project and build the compiler. Using it to migrate a system, 1.2 million lies of code, written in REALIA COBOL from 1986. So far 25 modules have been compiled with only minor changes to the source. Using OpenCOBOLIDE to edit, compile and test each system component. If anyone is interested I can provide a Windows self install exe to install the compiler under WINDOWS 7,8 and 10. Minor changes to OpenCOBOLIDE configuration will provide a integrated development environment. The original system used a screen management system written by the folks at NORCOM back in 1985. Great product which simplified full screen development under MS-DOS. For the conversion to GnuCOBOL I will be using they new package GUIScreenIO. Simplifies the development of COBOL programs using GnuCobol for WINDOWS. While is is not opensource, the product, it is not priced out of reach and, for the time saved, it is well worth the cost. screenio.com.

    So far no complaints. Have used it to write a farily extensive program on Linux and FreeBSD and it works just great!
