Backing up in a foreach loop.

ramziabboud has asked for the wisdom of the Perl Monks concerning the following question:

I am looping through a hash: foreach $key (sort (keys(%myHash))) { ##some code; } Can I send control back to the top of the loop without advancing an element in myHash? To say it another way, can i run ##some code; again with the same $key value? Does something like a back; exist?

As mentioned in the ChatterBox, you want `redo`. `foreach $key (sort (keys(%myHash))) { ... if (condition) { # Start over without advancing. # $key retains its current value. redo; } ... }` [download]	[reply] [d/l] [select]
