ChardScript While Loops

ChardScript Loops

ChardScript has two primitive loop commands:

• while loops

• for loops

The while Loop

With the while loop we can execute a set of statements as long as a condition is true.

Example

Print i as long as i is less than 6:

call i = 1
while i < 6 then
  echo(i)
  call i = i + 1
end

Note: remember to increment i, or else the loop will continue forever.

The stop Statement

With the stop statement we can stop the loop even if the while condition is true:

Example

Exit the loop when i is 3:

call i = 1
while i < 6 then
  echo(i)
  if i == 3 then
    stop
  end
  call i = i + 1
end

The continue Statement

With the continue statement we can stop the current iteration, and continue with the next:

Example

Continue to the next iteration if i is 3:

call i = 0
while i < 6 then
  call i = i + 1
  if i == 3 then
    continue
  end
  echo(i)
end
