Arnold J. Trembley - Biographical Data


I was born in St. Louis, Missouri in 1951, graduated from Webster Groves High School in 1969, and from Northern Arizona University in Flagstaff, Arizona in 1973 (B.S. in English, minor in Anthropology). I also earned a Certificate in Data Processing from Florissant Valley Community College in 1979. I have been programming professionally since then, primarily in COBOL in manufacturing and then financial applications in an IBM System 370 Mainframe environment (now System Z). I have worked primarily with the MVS/ESA operating system (later called OS/390 and now z/OS) and CICS through CICS /Transaction Server 5.x. I also have some experience with System 370 Assembler (HLASM), JCL (MVS, OS/390, z/OS), VSAM, DB/2, MQ/Series, CA-Endevor, DOS/VSE, VM/CMS, Basic, C, Series/1 RPS (Realtime Programming System), Series/1 MTM (Multiple Terminal Manager) and Series/1 Assembler.

From 1979 until 1986 I worked for UMC Industries, later named Unidynamics Corporation, and briefly for National Vendors (a Unidynamics subsidiary), following the purchase of Unidynamics by Crane. During this time period I programmed primarily in COBOL for manufacturing order entry and inventory/MRP (Material Requirements Planning) systems, on both IBM Series/1 Minicomputers and an IBM mainframe with DOS/VSE and VM/CMS operating systems. My duties later included CICS technical Support, VM/CMS security administration, and acting DBA (DataBase Administrator) for the Cincom TOTAL database, for which I installed release 8.15 and enabled CICS Dynamic Transaction Backout and Emergency Restart.

Since 1986 I have been working for MasterCard International where I learned a great deal about Command Level CICS COBOL programming in a realtime, conversational mode with BTAM, VTAM/SNA, and now TCP/IP network connections. My experience includes pseudo-conversational CICS programming with BMS maps, as well as conversational CICS programming with long-running tasks for VPN network communications. I also participated in a large Year 2000 project that completed successfully.

I retired from MasterCard in August, 2016, after turning 65. Sadly, my long-time girl-friend, Gwendolyn Douglas Bruce, passed away in January of 2016, and it is impossible to describe how much I miss her.


My other interests include guitar, ukulele, photography, reading, movies, and Contract Bridge. In the early 1980's I regularly competed in duplicate club games and occasionally in local Contract Bridge Tournaments, and I plan to resume playing Bridge in the near future.

I am also Creve Coeur township committeeman for the St. Louis County Libertarian Party Central Committee. I was appointed to fill a vacancy in 1995, elected to a four year term in 1996, and re-elected in 2000, 2004, and 2008. Township Committeeman is a party office, not a government office, although candidates must file for office in St. Louis County in order to appear on the ballot.

In 1998, I ran as a Libertarian for Missouri State Senate, District 24 (Creve Coeur, Ladue, and University City) and finished last in a three-way race.

In the year 2000, I ran for Missouri State Treasurer, and finished third out of seven candidates. In the year 2002 I ran for for Missouri State Auditor and finished third out of five candidates.

Now that I am retired, Politics is less interesting and I have no plans to run for office again.
