Behavioral analysis
OR
—used to describe a selection condition where only one sequence of func-
tional behavior will be performed. The logical path of execution is determined 
by the state of data item or resource and the conditional selection criteria.
LOOP
—used to repeat a sequence of functional behaviors until a condition is met 
that terminates the repetitive behavior, and the subsequent function in sequence 
beyond the 
LOOP
 is executed.
LOOP EXIT
—used to evaluate if the condition has been satisfied to cause the 
LOOP
 behavior to terminate.
ITERATE
—similar to a 
LOOP
, used to repeat a sequence of functional behav-
iors a specified number of times. When the specified number of iterations has 
be achieved, the looping behavior terminates, and the subsequent function in 
sequence beyond the 
ITERATE
 is executed.
