in thread while loops

No, not at all - Your code will only pass through a single iteration of the loop as on the first pass, the value of $num is added to $num. The result is that $num equals 40 and the while loop is exited. I think you may have been meaning, ignoring formatting syntax errors ...

$num = 20; while ($num < 30) { print "num is $num\n"; ++$num; }

Although, good pick up on the syntax error with the line - $while($num<30){ - Although this had been addressed previously within this thread.


perl -e 's&&[@.]/&&s&.com.&_&&&print'
