Post NXT RCX Hybrid Help
I've finally been able to get my robot to go forward using a NXT brick and 2 RCX motors.
But how do I get my robot to go straight using a NXT brick, 2 RCX motors and 2 RCX rotation sensors?

Essentially, how do I implement things like motor encoder, and motors sync commands with the RCX rotation sensors and the 2 RCX motors using ROBOTC to get precise movements?

Below is a ROBOTC RCX Sample Program for the Rotation Sensor. However when I tried to download it to my NXT it gave me an error message, next to the "ClearSensorValue..."

So I erased "Clear" form "ClearSensorValue" and then I set "SensorValue(rotationSensorA)" equal to zero, and this finally allowed me to download the program to my NXT.

Yet, the robot still didn't go straight :/
Can anyone help me?

task main()

// This is what the Sample Program said originally,
//Which I later changed to:
//SensorValue(rotationSensorA) = 0;
//SensorValue(rotationSensorB) = 0;

while(SensorValue(rotationSensorA) < 320 && SensorValue(rotationSensorB) < 320)
motor[motorA] = 100;
motor[motorB] = 100;
