Home - About RexxLA

The Rexx Language Association was established to further the understanding and use of the Rexx programming language. With the release of Object Rexx and NetRexx, RexxLA has expanded its mission to include these languages as well. The Association is headquartered at the Research Triangle Park in North Carolina, and is international in scope with members throughout the world. Supported by a dedicated group of volunteers, the Rexx Language Association provides many benefits for its members. The original Call for Participation in the formation of RexxLA kindly supplied by Mike Cowlishaw.

RexxLA sponsors the annual Rexx Symposium which features presentations by recognized Rexx experts and practitioners, interesting products, and an opportunity to network and to learn from people who share your enthusiasm for Rexx. All of the major Rexx vendors attend, giving you the opportunity to interact directly with them and provide them with valuable feedback from the field.

From the very first, the Rexx Language Association has been an active member of the committee working on an ANSI Standard for Rexx. That Standard was published in 1996. Your membership gives you a voice in maintaining this very important work.

If you write sophisticated applications in Classic Rexx, Object Rexx, or write your Java classes in NetRexx, or simply use Rexx to make your life easier on any platform, the Rexx Language Association has much to offer you.

RexxLA mourns the loss of Kermit Kiser

On behalf of the Rexx Language Association, I would like to offer my condolences to the family and everyone who has known Kermit. Kermit has been an active member of the NetRexx mailing list. Since its open sourcing he has been the chief architect and maintainer of the NetRexx translator and has added many improvements. Apart from our contact on the mailing list and in online project meetings, I came to know Kermit in person when we both visited the Aruba RexxLA symposium in 2011, when we were excited of our favorite computer language being open source. I will never forget our last dinner at the L.G. Smith Steakhouse, with Terry and Rony also present. We will remember him as a kind and very knowledgeable person who enormously enjoyed his work on Rexx.

RexxLA mourns the loss of Mark E. Miesfeld

On behalf of the Rexx Language Association, I would like to offer my condolences to the family and everyone that has known Mark. Mark was a well loved and highly esteemed member of our Rexx community. His contributions to ooRexx and especially Dialog Manager have been extensive. Although most of our community only knew Mark through our mailing lists, he will be deeply missed.

We remember Mark as a kind, helpful and brilliant person.
