I moved this from the other forum as I think it's a bug.

I created a very simple agent:

Agent

When I tried to update the communications code, i got the following error:

Error

Here is the log:

ArduinoCompile.ino: In function 'void SendInputs5()':
ArduinoCompile.ino:181:36: error: 'string0' was not declared in this scope
Error compiling.

And the code lines from the INO file:

Code:

void SendInputs5()
{
  Serial.print("UPD:5");
  Serial.print(":");  Serial.print(f[1]);
  Serial.print(":");  Serial.print(string0);
  Serial.print("\n");
}

Update

If I assign the output in the setup code the error goes away:

assign

However is I declare a byte array in the declaration block, the error returns:

Error

Changing byte to unsigned fixes the error:

BTW I just found that passing a size to the array appears to work:
