*********************************************************************** Another fault corrected in sim900al.ada --------------------------------------- While using Terry Froggatt's simulator of the Elliott 903 to run an ordinary assembly-coded program instead of an Algol program, another fault came to light which has been corrected in the attached program called sim900AL.ada and its companion, sim900al.exe. It affects multiplication of the accumulator by a number equal to -1.0 in the store; this was the trouble supposedly cured by the previous correction, but through carelessness the latter had been wrongly applied. The code using the constant, 242144, has been changed to use 262144, 2^18, and simplified too. Oddly enough the bad version affects the calculation of ln(0.2) only in the 6th decimal place, but the fault did cause a simulation of the EDSAC to loop during an EDSAC division subroutine where the divisor had a leading "1" bit followed by 18 or more "0" bits. This occurred during the execution of Hartee's 1946 ENIAC program adapted for the EDSAC. DGNH [ed CPB] 12-SEP-1998 ***********************************************************************
