Setting-up early computer programs: D. H. Lehmer’s ENIAC computation

Abstract : A complete reconstruction of D.H. Lehmer's ENIAC setup for computing the exponents of p modulo 2 is given. This program served as an early test program for the ENIAC (1946). The reconstruction illustrates the difficulties of early programmers to find a way between a man operated and a machine operated computation. These difficulties concern both the content level (the algorithm) and the formal level (the logic of sequencing operations).
