Recently I have been taking a look at GnuCOBOL (formerly OpenCOBOL), which looks like the free COBOL compiler for Windows that I've been waiting for all these years. There will be a link for OpenCOBOL 1.1 (06FEB2009) below.
I have also built the newer GnuCOBOL 1.1 compiler (20JAN2014) from source code available from the GnuCOBOL/OpenCOBOL project on Sourceforge.net. The compiler has been tested with the GnuCOBOL version of the NIST (National Institute of Standards and Technology) COBOL85 test suite and passes 9,011 out of 9,129 test cases. Please see the link below for a Windows installer for GnuCOBOL 1.1.
I'm also working on building GnuCOBOL 2.0 with MinGW (25OCT2015). There's an early version available below for download if you want to try it out.
There's a free Interactive Development Environment (IDE) for OpenCOBOL/GNUCOBOL written in Python, for Linux, Windows, and Mac OSX. The Windows installer includes GnuCOBOL 1.1 in additiona to the IDE. This is probably the easiest way to get an easy-to-use COBOL compiler for Windows. You can also install GnuCOBOL 2.0 in another folder, and change the settings in "OpenCOBOLIDE" to use GnuCOBOL 2.0 instead of GnuCOBOL 1.1.
For anyone who might be interested, I have a version of the Unix CAL.EXE calendar utility, reimplemented in PowerBasic as PBCAL.EXE for 32-bit Windows XP or 64-bit Windows 7.

As of Sun-21-Feb-2010, I have moved my pages to 50Webs.com, since my previous provider no longer supports personal web pages. I can also be found on LinkedIn and Facebook.
I finally replaced Netscape with Mozilla Firefox and Thunderbird
as my default browser and mail/news reader. And I've been
trying to play the guitar again, but it is difficult to find
enough time to practice. A good friend gave me a Fender Squire Stratocaster as an incentive. Recently, I've been having some fun playing Ukulele.
I receive emails from programmers in India with COBOL questions, which is very gratifying to me. I
hope the comments I provide to other working programmers are helpful.
work, I recommend my page on "COBOL Runtime Efficiency",
which includes links to some additional performance anecdotes
(including Leif Svalgaard's excellent article on Sorting
Algorithms). The Programming Resources page has been updated to
include links to "www.opencobol.org" and the "Hybrid XE Editor"
(an SPF clone) for PC. There is also a sample COBOL program for converting IBM OS/VS COBOL source code
to IBM VS/COBOL II source code.

Research Corporation website. I recommend this site to anyone
with concerns about Internet privacy and security.
