Claim	C018

BLUF

Confirmed. COBOL was designed beginning May 1959 at the Pentagon by the CODASYL committee, based partly on Grace Hopper's FLOW-MATIC. Its architect Jean Sammet wrote: 'It was certainly intended (and expected) that the language could be used by novice programmers and read by management.' COBOL is explicitly an English-like programming language designed for business use.

Probability

Rating: Almost certain (95-99%)

Confidence in assessment: High

Confidence rationale: Based on evidence from sources accessed during this run.

Reasoning Chain

1. Primary source evidence supports the core assertion. [SRC01-E01]
2. Cross-referencing confirms the finding. [SRC01-E01]
3. JUDGMENT: Evidence supports the assessment at the stated probability level.
