while loops allow you to execute a group of statements so long as a statment still evaluates to true.
Here's a quick example;
print "num is $num\n";
this will print out
num is 20
num is 21
num is 29
then num is incremented to 30 which is no longer less than 30
so the code within the while statement is not executed and
execution jumps to the next statement outside of the while statement.
If you think you know all about while statements learn about his less popular brother until.
Edit Wed Aug 1 07:07:10 EDT 2001 - Petruchio Changed PRE tags to
CODE tags, added whitespace.

changed '$while' to 'while', because this is in our Tutorials
section, and should be accurate.
