Statement of bias, I write the OpenCOBOL FAQ. I respect and admire this product, have since day of discovery. Endless potential for COBOL, endless. Well documented (Gary's guide is a world class COBOL document) and open to anyone that cares to try.

After writing in Cobol since my TI 990 days and then HP UX Cobol, RM and Micro focus I was excited to use to GNUCobol. After 2 days of dealing with all of the OpenCobolIDE meaningless compiler error messages and the lack of GNUCobol maintaining any ANSI Cobol standards I finally gave up. The Cobol language, in my opinion, is still one of the finest for business applications but this GNUCobol application is absolutely horrible. Looks like a bunch of amateur C++ programmers tried to write a Cobol cross compiler without understanding how Cobol should be written.

The team did a nice job in implementing a version of COBOL which matches the vast majority (not to say all of them) of MS-COBOL and Microfocus COBOL features. Being a nostalgic, I thought that I would no longer be able to exercise my hobby of programming in a platform like that - and you guys made it happen ! So congratulations for dedicating your off time to this - we, COBOL programmers and former programmers are the ones who benefit from that (not to mention the end users). As a former MS-COBOL 80, Microfocus COBOL and BLIS-COBOL programmer, I strongly recommend GnuCOBOL. And btw, if there is interest in using a screen editor/generator which is able to translate screen layouts into a SCREEN SECTION GnuCOBOL code, stick to EDITEL, a program of my own development also listed in Sourceforge for FREE.Reply from GnuCOBOL

I have just started using GnuCobol this year. I am still learning much about the implementation but the support it covers from IBM to MicroFocus and others is just incredible. I wish to thank the team who tirelessly worked on this and I do hope they get their much deserved due for doing this. Amazing!

GnuCOBOL, formerly OpenCOBOL, is an open-source COBOL compiler that is compatible with Windows, Linux, and macOS. COBOL, or Normal Business Situated Language, is a business-situated programming language that has been used since the last part of the 1950s. GnuCOBOL is effectively maintained and developed by workers in the local area who are focused on safeguarding and enhancing the COBOL language to meet the needs of current processing. The project's goal is to offer a free, open-source alternative to commercial COBOL compilers to more developers and users. GnuCOBOL is a good compiler that can be used to build a wide range of business applications. It has features and capabilities specifically designed to address the needs of COBOL engineers, and it has areas of strength for a number of clients and donors who are satisfied with its ongoing development and change.Reply from GnuCOBOL

Excellent!

Thank you for providing this amazing software for free!

Very good implementation of COBOL. Developers appear to be very active improving and adding features. OOP is not available yet but that is not unusual ILE COBOL for the IBM iSeries systems implements only 1985 standard with 1989 and 1993 improvements but does not support any 21st century standards and thus has no classes, methods, or properties. GNU COBOL implements 2002 and 2014 with only the exclusion of OOP. Both Fujitsu and Micro Focus implement OOP via .net while GNU COBOL is decidedly multi-platform so .net is not an option for them.

Hi! There are more information of install with red hat? I have so many issues with that, and I need install gnucobol in that! Thanks! It's a good project!Reply from GnuCOBOL

Decent language support. Could be nice if the syntax trees were a bit easier to extract, but I managed. Version 3.1 didn't pass all NIST tests for me. Also found an overzealous optimization.Reply from GnuCOBOL

using GnuCOBOL 3.1.2 under windows 7 and works like a charm! but if you try this on Linux eg Void I am only getting a scrolling ERROR ... ERROR what you crackheads? Was so difficult to display something meaningful when there is an issue? get some life .Reply from GnuCOBOL

This cobol is easy to use once you get install. The support is very good.

Important project: about 35% of "production" code is in COBOL, and it processes about 80% of all transactions (e.g., ATMs, telephone calls), so making it robust will allow many companies to thrive. Was easy to integrate (and extend) in my COBOL translation project. In need of thorough testing, as the quality is still "Just OK". Wish I had more free time to help :-)
-
The development team has excellent communication and quick interaction and answers to questions asked. As for the quality of the compiler I found it very good.

This review is for the work done by the maintainers of GnuCOBOL. I really want to highlight that I like GnuCOBOL but I hate COBOL language itself.
-
Extraordinary example of Programming techniques.
-
GnuCOBOL allows us to change C backend depends on a computation task and reach highly optimized code, thank you a lot!
-
A free COBOL Compiler with all the features and cross-platform ready. Community help is also exceptional. Thank you all.
-
GnuCOBOL (formerly OpenCOBOL) is a great project, highly recommended.
-
A very interesting and useful Project. I used this Compiler with a lot of fun.

COBOL PRINTING COMMANDS DO NOT WORK IN OPEN COBOL ON WINDOWS !! WHY BECAUSE OF THE LIMITATION OF GNU C ,C++ AND JAVA! THE LANGUAGE SPECS DO NOT INCLUDE PRINTING. AS PART OF THE LANGUAGE!! MOST C AND C++ PROGRAMMERS DO NOT EVEN KNOW HOW TO PRINT TO A “REAL PAPER PRINTER” PRINTING IS NOT INCLUDED IN THE LANGUAGE PERIOD!! MICROSOFT INCLUDES PRINTING CONTROLS AND APIS IN THEIR LANGUES: C++ C# THE REPORT WRITER SECTION IN THE MANUALS EXPLAIN A SPOOLER AND KLUDGE SOLUTION, THE “CUPS” PRINT SPOOLER I FOUND WAS AN APPLE PROGRAM NOT A WINDOWS PROGRAM? SO WHAT YOU NEED TO DO IS OUTPUT A TEXT FILE AND THEN PRINT IT ON PAPER USING: THIS SOLUTION WORKS ON ALL COMPUTERS AND ALL OS: 1) MICROSOFT WORD OR APACHE OFFICE 2) OR EXCEL OR APACHE OFFICE 3) MAKE TEMPLATES FOR FORMS TO PRINT 4) USE A PDF PRINT PROGRAM: FOXIT READER TO SAVE PAPER 5) USE REPORT WRITER PROGRAMS TO PRINT ELABORAGE REPORTS AND GRAPHICS I THINK THE GNU COBOL GROUP SHOULD JUST ADMIT THAT BECAUSE OF C AND C++ LIMITATIONS THAT THE COBOL PRINT COMMANDS ARE NOT GOING TO WORK AND JUST DUMMY COMMANDS USED TO AVOID COMPILE ERRORS!!! THIS WOULD SAVE PEOPLE A LOT OF TIME AND AGGRAVATION RATHER THAN PRETENDING THAT THE PRINTER COMMANDS WORK! THE GNU COBOL GROUP SHOULD PIC AN OPEN SOURCE REPORT WRITER PROGRAM AND INCLUDE IT IN THEIR DISTRIBUTION ---------------------------------------------------------------------------------------------------------------------------------- REPLY TO SYSTEM MAINTAINER: ON A WORKING COBOL COMPILER YOU: READ A FILE : READ WRITE A RECORD WHY ARE YOU PRETENDING THAT YOU DO NOT KNOW WHAT "PRINTING COMMANDS" MEANS? STANDARD ANSI COBOL, IBM COBOL ETC HAVE REAL WORKING COMMANDS TO WRITE TO A "PAPER PRINTER" AN IBM, HP OR CANNON PRINTER. (NOW DO YOU UNDERSTAND WHAT A "PRINTER" IS. NOT FAKE COMMANDS THAT DO NOT WORK!!! THIS IS NOT A USABLE COMPILER, I CAN NOT TAKE MY IBM COBOL PROGRAMS AND COMPILE THEM AS A USABLE COMPILER. COBOL IS A BATCH PROCESSING COMPILER, ITS PURPOSE IS TO WRITE FILES AND PRINT PAPER. ITS NOT JAVA OR HTML OR VISUAL C#, DO YOU UNDERSTAND MY COMMENT NOW. --------------------------------------------------------------------------------------------------------------------------------------------------- Instead of using the standard c++ gnu excuse "printing on a real paper printer is not part of c or c++", you can fix the printer problems with your compiler. Both microsoft c++ and c# both include "writing to a real paper printer", hp, cannon brother "printers etc! You should build your compiler on a microsoft platform, so the compiler is usable and not incomplete gnu junk! visual c++ and c# and all the other tools you need to build the compiler for linux and windows are included in the visual studio community edition (free version of visual studio). until you fix your printer problem, this is just more gnu junk.Reply from GnuCOBOL

Really cool code. Now if I can find someone who's using this compiler and needs a programmer to write some code.

This is an excellent product. I just finished using GnuCOBOL in an undergraduate course about business systems. The students completed twelve modest programs in COBOL over the semester. I had no problems with the compiler or the execution. I did round up one or two issues, which I'll file later as bugs/requests but, in general, it worked flawlessly. These issues came about from very poorly formed programs and the compiler not recovering. There was no instance where a proper program failed to compile and execute. The only sad thing is now I will likely shut down the VMS system I was using for a COBOL compiler. One less place for people to go learn VMS. :-D Thanks for a great effort.

GNU Cobol does everything I need to do and the community is very helpful.

6 month ago I started learning COBOL via GNUcobol being tired of those languages which use curled brackets. I installed in on SUSE, UBUNTU and MINT and it ran !!! Opencobilide and garys manual are very helpful to make non-frustrating experieces. The help-forum is superfast and they dont blame you asking beginners questions. If you have to do really dataprocessing (which means not writings apps for Iphones) GNUcobol is the compiler for professional DP. MF wrap up yourself warmly.

Used for a COBOL training program. VSAM files worked very well. Great job, thank you !
