ENIAC U. S. Army
It is now a simple matter to consider the operation boxes, one at a time, and write the succession of orders which will cause the machine to carry out the computations described in that operation box. For the convenience of the reader we have written these orders both by name and by number for one example. (See Tables 7.I and 7.II) The reader can learn the code by making a table 20 columns wide and translating the code numbers into the movement of numbers among these columns.
Finally, it is advisable to prepare a test run by giving all the variables numerical values and carrying out one typical computation for testing occasionally that the ENIAC is operating properly. Such a test run has been computed for this problem but it does not seen necessary to include it in this report.
