Application variables

As well as the console having variables, applications can have variables which we can read (but not write) from the console:

connect app3 other-warrant.xml    # Connect to a new application
echo $app3.somevar                # See the value of its "somevar" variable
set myvar=$app3.somevar           # Set a local variable to its value

In the lines above, $app3.somevar should be read as $ plus app3.somevar. It has nothing to do with the console variable $app3.
