do while statements

I’m unable to get the do{ statements }while(expression) to work using ROBOTC 4.55 and a Cortex (Clawbot).
Has anyone had success using this control structure? If so, any short sample code would help tremendously.
Thanks,
Dave

The do-while construct is very similar to a while construct except that the test for completion is moved to end rather than being at the beginning.

So code like this

task main()
{
    while( true ) {
      motor[port1] = vexRT Ch2 ];
      
      wait1Msec(10);
    }
}

could be rewritten to look like this.

task main()
{
    do {
      motor[port1] = vexRT Ch2 ];
      
      wait1Msec(10);
    } while( true );
}
