Combining 4 motor commands into 1 command

#1

I know there’s a way to reduce the amount of lines of code regarding motor commands. Our robot has 4 chassis motors that repeatedly move the robot forward and backward with all 4 motors turning in the same direction at the same speed. I believe there is a way to reduce the 4 lines of code that direct each motor individually to only one line of code. How do we do that?
thanks

It looks like this was already answered here.

but here’s an example.

void
setMotors( int speed ) {
  motor port1 ] = speed;
  motor port2 ] = speed;
  motor port3 ] = speed;
  motor port4 ] = speed;
}

task main()
{
    // Using a function
    setMotors( 100 );
    wait1Msec(1000);
    setMotors( 0 );

    // or all on one line
    motor port1 ] = motor port2 ] = motor port3 ] = motor port4 ] = 100;
}
