while

Syntax
while ( expression ) statement
Description

The while statement is a looping statement. It repeatedly executes the specified statement while the specified expression evaluates to true (any non-zero value). The while statement terminates when the specified expression evaluates to false (the value 0) or it encounters a break statement.

NOTE: The specified statement may not be executed if the specified expression initially evaluates to false (unlike the do-while statement, which always executes its specified statement at least once).

Use a statement block in the form { statement ... } to execute multiple statements in the loop. Quest recommends using a statement block for readability.

Examples

This prints the values 1,2,3,4,5:

x = 1; 
while (x <= 5) print(x++);

This prints the values 1,2,3,4,5 and uses a statement block:

x = 1; 
while (x <= 5) { 
   print(x); 
   x++; 
}

This prints the values 1,2,3 because the break statement terminates the loop:

x=1; 
while (x <= 5) { 
   if (x > 3) break; 
   print(x++); 
}

(See Use the While Loop for more usage examples.)
