beginning of the loop's execution, the loop will continue to repeat itself. If the condition becomes false by
the time the loop executes, or repeats execution, the loop will no longer execute, and the protocol will
continue on to the next step following the End Loop box.
Conditions are checked before a loop executes its process, and will re-evaluate the condition before
repeating the process each time to determine if the loop should run.
Note that any protocol-defined or valid interface variable can be used in the conditional statement for the
loop. Invalid variables will not be accepted.
