while loop

'''while'''('condition','body') - Function of iterations. The cycle carries out a 'body' while the 'condition' is true. 

'''ADVICE: Choose it from the Programming palette'''

'''IMPORTANT''': Inside the 'body' ([[line]] could be used) the 'condition' must change from '''true''' (different than zero) to '''false''' (zero) otherwise we can have the endless (never ending) loop. The only way in this case for while or [[for]] loop is to interrupt the calculation by choosing

As a '''general rule''', if the calculation is too long, make double checking of the '''loops'''.

Here is a simple example of using '''while''' loop:
