If you post code, I can help

DEVIATION_LEFT = false;

LoopStart:
sleep(1);

if (DEVIATION_LEFT == true) {

  print(DEV_PITCH + "LEFT DEV  ");
  Digital.set(d11, true);
  sleep(1);


}

continue LoopStart;

Thankyou DJ.  I have multiple scripts that normally run.  This is one of them.  I have found that if I open the script up, it gets "corrupted" and sends an error code.  Of the scripts that I did not open since the revision download, they run fine.  The above code error message is LoopStart "undefined".

Unfortunately, that would never have run in any JavaScript environment. The reason is the label needs to be directly before a loop. I believe the confusion you have is moving from EZ-Script to JavaScript and misinterpreting the label: functionality. That's easy to do because EZ-Script was terrible

A label: is defined in JavaScript quite differently, see here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/label

And more specifically, someone attempting to use it in the similar fashion and realizing the label: needs to be applied directly before a looping statement, here: https://stackoverflow.com/questions/6393648/why-is-this-labeled-javascript-continue-not-working

Here is your code re-written. Keep in mind, as the code comment says, DEVIATION_LEFT is always false. So the IF condition will never be met.

// loop for ever and don't do anything because DEVIATION_LEFT is always false

var DEVIATION_LEFT = false;

while(true) {

  sleep(1);

  if (DEVIATION_LEFT == true) {

    print(DEV_PITCH + "LEFT DEV  ");
    Digital.set(d11, true);
    sleep(1);
  }
}

Perhaps if you're communicating with other controls, you'd want DEVIATION_LEFT to be public across the entire project. In that case, use getVar() and setVar(). Such as....

// loop for ever and don't do anything because DEVIATION_LEFT is always false
// unless DEVIATION_LEFT is set from another control to TRUE

setVar("$DEVIATION_LEFT", false);

while(true) {

    sleep(1);

  if (getVar("$DEVIATION_LEFT") == true) {

    print(DEV_PITCH + "LEFT DEV  ");
    Digital.set(d11, true);
    sleep(1);
  }
}

All my scripts are in blockly.  They do not run.  This version of ARC does not run my Blockly Scripts. What am I to do? Jack

Don't use goto/label, as per the manual for JavaScript states. Unless you're using it for the correct intended purpose, which is outlined in the JavaScript manuals.

The solution would be to use the Loop Forever block, which produces while (true) loop

PITCHBACK = false;

SCAN:
IR = (ADC.get(adc7));

sleep(1);

if (IR <= 65) {

  PITCHBACK = true;

  continue SCAN;


}

PITCHBACK = false;

continue SCAN;

On this script an error msg "unble to get"(ADC 7). It is connected to the EZB4.  I have tried recoding it using Blockly from this current ARC. My scripts ran perfectly earlier this morning before the download.  Does a  previous version exist that I could use?  I would say that the last update I did was 3-6m ago.  I tried ARC 4.2 with the same results. Thanks Jack

There indeed seems to be a naming mismatch between the Blockly and JavaScript using ADC.get and ADC.getADC. I'll fix that for the next release. There will be a new Beta release candidate this evening. I recommend switching to that channel

Many Many Thanks. Jack
