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.
