About FLOW-MATIC
FLOW-MATIC was the first English-like programming language, developed by Grace Hopper and her team at Remington Rand from 1955-1959.
- Ran on UNIVAC I and UNIVAC II
- Direct ancestor of COBOL
- First to use English words as code
- Proved computers could understand natural syntax
Features COBOL Killed
FLOW-MATIC had revolutionary features that COBOL dropped:
- SET OPERATION - Runtime flow modification
- X-I Sections - Inline machine code
- EXECUTE - Subroutine mechanism
- Single-letter aliases - Concise file refs
- Block integrity - Built-in validation
The Ian Index
This page is part of The Ian Index - a comprehensive archive preserving computing history and documenting the "forgetting cycle" where innovations are lost and later reinvented.
- Original documentation preserved
- Working implementations
- Historical analysis
- Named after Ian, who believed in remembering
More FLOW-MATIC Projects Coming Soon
We're actively expanding the FLOW-MATIC implementation with more examples, features, and historical recreations. The archive grows weekly.
