Hopper retired from the Navy in 1986. After the war, she was still interested in computers. Hopper worked at Remington Rand. She worked at Sperry Corporation later. She did not return to her teaching career after the war. She continued working on software for the other computers. She also served as an officer in the Naval Reserve. She worked on the UNIVAC, the first large-scale commercial computer. Hopper's work led to the development of the FLOW-MATIC. The  FLOW-MATIC was the first English-language data compiler. Hopper's work on FLOW-MATIC helped her later work with Common Business Oriented Language (COBOL). Hopper’s work translated the computer language into words we use that the computer will also understand.
