break

Description

Interrupts a do-while loop, a for loop or a switch statement.

Usage

break;

Program Structure

break can be used in two ways, depending on the context. Within a do-while or for loop it exits the loop before the loop expression has become false. Within a switch statement it is used to skip the rest of the case: tags.

Example

// The for loop will only run 5 times. Afterwards,
// a will be 10 (0+1+2+3+4).

var i, a = 0;

for (i=0; i<10; i++)
{
  if (i==5) break;
  a += i;
}


// So will this do-while loop. Again, a will be 10 afterwards.

var i = 0;
var a = 0;
	
do 
{
  if (i==5) break;
  a += i;
  
  i++;
}
while (i<10);


// Using break correctly is important in switch statements,
// otherwise all cases are executed. 
//
// Outputs "It's a number.".

var x = 5.5

switch(typeof(x))
{
  case DT_INT:
  case DT_FLOAT:
    println("It's a number.");
    break;
  
  case DT_STRING:
    println("It's a string.");
    break;
  
  default:
    println("I don't know what it is.");
}
