Outputfacilities

One of the first problems that occurs when output facilities are developed for a program package like SMS is identifying output uniquely. In experimental programming a great deal of test output is generated, which is often difficult to associate with a particular state of the program by the run or experiment identification alone. To avoid confusion, the output must be made distinguishable, independently of experiment identification which, for convenience, will often be maintained. The easiest way to do this, isto mark each kind of output with the actual date and clock time. In SMS this is achieved by using the subroutine DATUHR. It generates a heading line as in fig. 9.1.1 for each kind of printer output, containing experiment identification and actual clock time, identical within each Monte Carlo run.
