Not shown as an Update in your OP:

I am getting syntax error at near ");" at while (0). How do you fix it?

To be honest, I find your reply quite unbelievable. Four monks responded to your post yesterday: davido (in Re: Perl Loops) answered the very question you're now asking; vinoth.ree (in Re: Perl Loops) showed a code example of how to do it; farang (in Re: Perl Loops) and rjt (in Re: Perl Loops) pointed you to documentation for this loop construct.

Go back and read the advice, code and documentation provided. Then make some effort yourself!

Also read "How do I change/delete my post?".

Update: Added the names of the four monks and links to their specific posts.

Dear Ken, Thanks for your input but I just updated my post to reflect where I needed the correction/help at. Thanks!

Forget about the code you have, start over, create a folder "one" with five files for.pl dowhile.pl while.pl dountil.pl forfor.pl and start filling them until you have a command of how they work; first you learn addition, then you learn multiplication

say one print a range of numbers; say 24 .. 42

say two print odds from 24 .. 42 and evens from 42 .. 84

say three same as two except avoid all use of range operator, use addition

say four same as two except only use subtraction
