Why COBOL? Real History & Why It's Still Running Today

COBOL stands for Common Business-Oriented Language — a name that describes its entire real design philosophy in three words. It was never meant to be a general-purpose language for every kind of programming; it was built, deliberately, for one specific real purpose: processing business data at scale, in a form readable enough that a manager, not just a programmer, could follow the logic.

The Real 1959 CODASYL Committee

COBOL's design began in 1959, driven by the CODASYL committee (Committee on Data Systems Languages) — a real, deliberate effort to create one standard business language that could run on machines from competing manufacturers, rather than locking a business into one vendor's own proprietary language. A six-person subcommittee did most of the real design work:

Three competing manufacturers, working together on one shared standard — a genuinely unusual real arrangement for the era, and a direct, deliberate answer to the "vendor lock-in" problem business computing faced at the time.

Two Real, Different Influences

COBOL wasn't invented from nothing — it deliberately combined ideas from two existing real languages. FLOW-MATIC, on which Grace Hopper served as technical adviser, contributed long, readable variable names, English-word commands, and the real, foundational idea of separating data descriptions from instructions — exactly the split that would later become COBOL's own DATA DIVISION and PROCEDURE DIVISION. COMTRAN contributed real arithmetic formula support, an improved IF statement, and — directly relevant to Chapter 3 of this course — the PICTURE clause itself.

COBOL 60: A Real, Specific Date

The finished specification was approved by the executive committee on 8 January 1960, then sent to the US Government Printing Office, which published it as COBOL 60 — the real, original standard every later COBOL revision built on.

Even this simplest possible real COBOL program already shows the shape Chapter 2 covers in full — four named divisions, appearing in a fixed order, each with a distinct real job.

Why This Matters Today, Not Just Historically

COBOL's real, continued relevance is genuinely striking. A 1997 estimate put roughly 200 billion lines of COBOL in active existence, running an estimated 80% of all business programs at the time. More recently, a real 2020 statistic found that COBOL processed 95% of the time a credit or debit card was swiped. Banking, insurance, and major government agencies — including the IRS, the US Treasury, and the VA — still run real, live COBOL systems today.
