Entering: To enter a case in a Bayes net, simply enter each of its findings.
Removing: To remove the current
case from a belief net, make sure no nodes are selected,
and choose Cases →
Remove Findings, or click
the 
toolbar
button. It will leave the net with no findings entered, and
if it is an auto-updating
net, then its beliefs will be updated to reflect that. If some nodes
are selected when you choose Remove Findings,
then only the findings for those nodes will be retracted.
Saving: You can save cases in files and read them back in.
Reporting: To create a text
table showing the current case, use Report
→ Findings.
Using other choices on the Report
menu you can control its appearance
and destination. To locate
all the nodes that have any finding, or just a likelihood finding, you
can select them.
