Any way to advance to an iterator prematurely?

Kurt Euler

All-

In the code below, is there an way to put a condition just before <do a big bunch of stuff?> that will cause the iterator to advance to the next x (the next line in control.txt) WITHOUT doing <do a big bunch of stuff>. I thinking something like "if field[0] != "test" read_next_line_in_file". I'd
rather not put <do a big bunch of stuff> in a giant if/end statement.



IO.foreach("control.txt") { |x|
field = x.chop.split('\t', -1)
<do a big bunch of stuff?>
}



Thanks!

(1..30).each do |x|
next if x == 15
puts x
end
