While statement
Sometimes you must repeat a list of statements as long as a certain
            condition holds true. In BI# you can use the while
            statement for this purpose. It expects a Boolean expression and a list of statements.
            This process uses a while statement to print the numbers
            from 1 to 5: 
#define EngineVersion 5.0
#define RuntimeVersion 5.0

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