It was said by Hopper to be "the basis for all subsequent programming languages" (She also said Holberton "was the best programmer" that she had ever known) Bergin 2000 from WTI: "What are you most proud of? The design of the instruction code of UNIVAC 1 and the code called C-10. I was in engineering in those days and I had just come from programming the ENIAC. That code was mostly designed at night while I was laying awake. My daughter said it was a form of psychology. I always stayed in the background and got most things done without people knowing that. I had to learn to speak out and it effects me today. We have sessions at the nursing home and I speak up and they all sit there." From WP Obit: "Late in life, Mrs. Holberton was credited for her efforts to make the language and equipment of programming user-friendly. After World War II, she created an instruction code, called C-10, that allowed for control of the new UNIVAC -- the first general-purpose computer -- by keyboarded commands rather than by dials and switches. While engineers focused on the technology of computing, Mrs. Holberton lay awake nights thinking about human thought processes, she later told interviewers. She came up with language using mnemonic characters that appealed to logic, such as "a" for add and "b" for bring. She designed control panels that put the numeric keypad next to the keyboard and persuaded engineers to replace the UNIVAC's black exterior with the gray-beige tone that came to be the universal color of computers." Abbott (1995) "The C-10 Code simply listed the instruction set of for UNIVAC. It also contained a simplistic chart of the timing cycles of the UNIVAC (alpha, beta, gamma, and delta time). Gamma and delta was when the instructions were executed. Alpha and beta time took care of stepping from one instruction to the next instruction, and initializing the instruction execution process."
