An attempt was made to eliminate the effect of overhead, by subtracting the time for a ``null'' program (one that was similar to the benchmark, but executed zero iterations of the main loop). The results are as follows: PROGRAM Before time After time Speedup factor ******* *********** ********** *************** APL 374 9.2 41 Basic 184 28 7 C #1 40 0.6 67 C #2 67 1 67 Subjectively, the effect on using APL interactively is quite spectacular.
