Kronzky
The boolean code that is used to evaluate the while condition can be preceded by code that executes a regular command. while {_a =_a + 1; _a < 10} do {...}

In non-scheduled environment, while do loop is limited to 10,000 iterations, after which it exits even if condition is still true. In scheduled environment no such limit exists.
