How to Create a While Statement in Perl

Perl's while statement is a form of loop which iterates as long as a condition remains true.

Instructions

1. Initiate the while loop by specifying the while keyword.

2. Specify the condition for continuing the loop in parentheses following the while keyword:
   while ($ok)

3. Provide the statements to be executed each time through the loop within curly brackets:
   while ($ok)
{
 :  $ok = ok();
}

4. Place an optional continue clause after the loop body, to specify statements to be executed after the body but before the while condition is evaluated.
