evaluates

false on the first pass, the loop does not execute.

Here is an example of calculating scalar product of two vectors, using the 

while

statement:

s = 0

i = 0
while i < n

s = s + a[i] * b[i]

i = i + 1

Probably the easiest way to create an endless loop is to use the statement:

while TRUE
