 As an example for the bytecode compilation the following listing shows the
 thermostat example given in Listing~\ref{lst:exmtask} compiled to bytecode.
-The left column indicates the position in the program memory.
+The left column indicates the position in the program memory. The \CI{endif}
+label is resolved to an address outside of the program space. This is not a
+problem since this is included in the stopping condition of the interpreter.
+When the program counter exceeds the length of the program, the task
+terminates.
