Break and continue

break exits the innermost while, repeat, or numeric for loop:

local number = 1

while true do
    if number > 3 then
        break
    end

    print(number)
    number += 1
end

continue advances the innermost loop without running the rest of its body:

for number = 1, 6 do
    if number == 3 then
        continue
    end

    print(number)
end

Its destination depends on the loop:

Loop	continue proceeds to
while	the condition
repeat	the until condition
numeric for	checked range advancement

Both statements target only the innermost loop and take no label or value. A nested local function creates a boundary; it cannot break or continue its caller’s loop.

In rc.3, a repeat that declares a body local used by until cannot also continue to that condition, because the skipped declaration might leave the condition without an initialized value.
