Loop and Break

Loop

loop creates an infinite loop with no condition. Use break to exit:

loop {
  if condition { break }
}

This is equivalent to while 1 but reads more naturally for “do until done” patterns.

Break

break exits a loop. It works in loop, while, and for blocks.

i = 0
loop {
  write(i)
  i = i + 1
  if i > 5 { break }
}

stop is kept as an alias for backward compatibility, but break is the preferred keyword.

Practical example

A common pattern: run an event loop that breaks when a flag is set:

running = 1
loop {
  cmd = read()
  if cmd == "quit" { running = 0 }
  if cmd == "help" { write("commands: quit, help") }
  if not running { break }
}

The flag running starts as 1 (true). When the user types “quit”, the flag goes to 0 and the loop exits on the next iteration.

Repeating timer with sleep

Using sleep@math to run something every 2 seconds:

count = 0
loop {
  write("tick", count)
  count = count + 1
  sleep@math(2)
  if count >= 5 { break }
}

Sleep takes seconds. The loop ticks every 2 seconds for 5 iterations.
