Re: using redo in an if/else statement

I was trying to reply this post, but then...I myself become really confused.

I first wrote "redo works with all 'iterators', like for, while, do", then I started to coding and test, however I was stuck with this piece of code:

use strict;

my $i = 1;
my $flag = 1;
do {
    print "$i ";
    if (($i ++ == 5) && $flag) {
        $flag = !$flag;
        #redo;
    }
} until ($i >= 10);

If I uncomment that redo, perl gave me "can't redo outside a loop block". (Perl was fine with for and while)

Did I miss something obvious, or that is just the way perl goes, (if that is the way perl goes, I don't buy their logic at all, "do {} unitl" is not a loop?)

I was bitten by that one too a while ago. `do {...} until (...);` looks like a loop but isn't one since `until` plays the role of a modifier and isn't a statement. Have a look at this for official confirmation. Hope this helps, -gjb-	[reply] [d/l] [select]
