Why don’t you just write a small program and test it out for yourself?

Cheers

I’ve not been visiting here for very long, but I suspect people will be  
quicker/more inclined to help if you provide the program you’ve created  
to test the issue/question.

Play with the following code – run it and see what it does… uncomment  
the “next if i \< 3” line, run it, and see what it does… recomment the  
“next” line, uncomment the “redo” line, run it, and see what it does.

for i in 1…5  
puts 'current value of i is: ’ + i.to\_s  
#next if i \< 3;  
#redo if i \< 3;  
puts 'end of loop and i is: ’ + i.to\_s  
end

Additionally, a quick Google search of “ruby redo next” will turn up
