In 2016 I retired after turning 65 and I'm now enjoying more leisure time for taking Adult Continuing Education Classes, playing Bridge, and learning to play guitar and ukulele.
Since early 2014 I have been working with GnuCOBOL (formerly OpenCOBOL), which is a free, open source COBOL compiler for GNU/Linux, Mac, and Windows. Please see the "GnuCOBOL/OpenCOBOL Downloads, Binaries, and Links" page below.
I have recently added several new downloads for the GnuCOBOL 2.2 (06SEP2017) Final Release and MinGW Build Guides, including a 64-bit version. Older GnuCOBOL 2.0 Release Candidate 2 downloads are still available, but earlier releases of GnuCOBOL 2.0 (Release Candidate 1 and earlier) have been removed. An installer for OpenCOBOL 1.1 is still available on that page.
The newest download available is GnuCOBOL 3.0 nightly build R2451 (pre-release).
For anyone who might be interested, I have a version of the Unix CAL.EXE calendar utility, reimplemented in PowerBasic as CAL.EXE for 32-bit or 64-bit Windows XP or higher, including Windows 10.

On Sun-21-Feb-2010, I moved my pages to 50Webs.com, since my previous provider dropped support for free personal web pages. I can also be found on LinkedIn and Facebook.
I replaced Netscape Navigator 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 sometimes difficult to find
enough time to practice. A good friend gave me a Fender Squire Stratocaster as an incentive. Recently, I've also 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 GnuCOBOL/OpenCOBOL. 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.
