31.10 Regression test

When preparing for the simulation batch run, since it was not the first time we were running

the RunFull simulation, we specified names for new and baseline simulation logs on the WTM

panel used to specify the names of the log data sets, as shown in Figure 31-163 on

page 1071.

We now compare the results of these two runs and see if there are any differences.

1. Enter the line command 0 to work with the output from the RunFull simulation, as shown in

Figure 31-170.

3. WTM displays the panel with the names of the log data sets to be compared and where to

put the results, as shown in Figure 31-172. Press Enter.
