Wait, I think I got it fixed.  If I simply remove the function name (LampCheck) at the top of the LampCheck sequence, and then call the sequence from the button, then I see the two sequences running concurrently. 

your ctl file is for a newer version.  Mine is... older.

Thanks, I resolved by splitting those functions into separate sequences.

So now I have a helper sequence:

function LampCheck()

   while (1)
      
      //--------------------
      
      // check the lamp current pin
      LampCurrent()


      // check the lamp power pin
      LampPower()
      
      //--------------------
      // now process the results

            // GPIO 1                  GPIO 2
      if (lampCurrent[0] == 0 && lampPower[0]) == 0)
      
         ? "Power not available/disconnected"
         v.lampStates.AddValue(-1)
         
      elseif (lampCurrent[0] == 0 && lampPower[0]) > 435)
      
         ? "Power available, lamp not connected"
         v.lampStates.AddValue(-2)
         
      elseif (lampCurrent[0] > 205 && lampCurrent[0] < 270 && lampPower[0]) > 435)
      
         ? "Power available, lamp off"
         v.lampStates.AddValue(0)
         
      elseif (lampCurrent[0] > 270 && lampPower[0]) > 435)
      
         ? "Power available, lamp on (flashing)"
         v.lampStates.AddValue(1)
         
      else
      
         ? "Other combinations wouldn’t be valid"     
         v.lampStates.AddValue(-3)
         
      endif
      
      ? v.lampStates[0]
      
      //--------------------
      // critical delay!
      
      delay(0.3)  // execute 3 times a second
      
   
   endwhile

This needs to run a couple times a second once started, parallel to the calling sequence.  I understand this is a call for (pun) the BeginSeq() command.

So here's a sample caller sequence:

beginseq(LampCheck)

? "started sequence"
Delay(.8)
? "delayed 0.8 seconds"
Delay(1.4)
? "delayed 1.4 more seconds"

endseq(LampCheck)

Yet when I start this caller sequence, it is getting stuck in the LampCheck.  The two sequences aren't running concurrently.

I'm unable to call a specific function from inside a sequence page from a control button.  

I would prefer to organize my functions that are related in a single sequence page.  What am I doing wrong?
