In 1946 Goldstine sat in on programming sessions with Bartik and Dick Clippinger and was hired to help implement Clippinger's stored program modification to the ENIAC. John von Neumann was a consultant on the selection of the instruction set implemented. This solved the problem of the programmers having to unplug and replug patch cables for every program the machine was to run; instead the program was entered on the three function tables, which had previously been used only for storage of a trajectory's drag function. ENIAC programmer Jean Bartik called Goldstine one of her three great programming partners along with Betty Holberton and Art Gehring. They worked together to program the Taub program for the ENIAC.
