When required by the declaration STATISTICS, the GLIDER produces an output with statistics of nodes and variables. This statistics are always displayed at the end of the simulation, but they can be shown at any time during the run by program indication or by an operator interruption that calls the Run Interactive Menu. Statistics for one run of the simulation example follows:

The title of the experiment is by default ``Basic Experiment". The user can put other titles by program (see instruction TITLE, 6.27) or from the Menu.
The total simulation time and the last time in which the Statistics were cleared (see procedure CLRSTAT, 7.4) are also shown.
If replications of the experiment are asked for, the number of the replication is given.
The date and time of the beginning of the execution and the computing time spent in the simulation are also recorded.
For the I type nodes the number of generated messages is shown.
For each EL and IL the number of entries, the actual length and the maximum length are displayed. The statistics show the mean length and its deviation, the maximum and mean waiting time of the messages in the list, its deviation and the time that the list remained empty.
For the E type nodes the mean time in the system of the messages destroyed at the node and its deviation are recorded.
In this example only the used time of the resources
are displayed, because no other variables in the STATISTICS were
requested. The statistics given are the mean and deviation of
the variables as a function of time, the maximum and minimum values,
the mean and deviation of the values and the actual (final) value.
