Bargraph update from a variable.

  This is what I've have in my com module:

  CASE AVR_CMD_MV:
             {
             STACK_VAR INTEGER nVol;
             
             if(find_string(iRX_Buff,'MAX ',1))  
              {//only held here for now.  use if there's a need for it and reason to increase levels above 16.
              REMOVE_STRING(iRX_Buff,'MAX ',1);
              
              nVol = atoi(iRX_Buff);
              if(nVol > 100)
               {
               sAVRm.sZM.nMaxVol = nVol / 10;
               }
              else
               {
               sAVRm.sZM.nMaxVol = nVol;
               }
              fnSend_Main_LVL(AVR_LVL_MAXVOL,sAVRm.sZM.nMaxVol);
              nMatchFound = 1;
              }
             else 
              {
              nVol = atoi(iRX_Buff);
              if(nVol > 100)
               {
               sAVRm.sZM.nMVol = nVol / 10;
               }
              else
               {
               sAVRm.sZM.nMVol = nVol;
               }
              fnSend_Main_LVL(AVR_LVL_MV,sAVRm.sZM.nMVol);
              nMatchFound = 1;
              }
             }
  

  In this module I just send levels back to the main, no strings or commands so in my Avr.axi which receives the levels sent by the com module I basically just do this for volume FB:

  fnAVR_DoSend_LVL(iUI_Indx,iLVL_Chnl,iLVL_Value,iAVR_Indx);
  

  Which updates any UIs on the same instance of the module. My variables are integers so they automatically round off the value since I don't need decimal precision and the master will automatically decide if it needs to send the level when you receive 85.5 and then 86, 86 will be sent on 85.5 and not again on 86 since the masters knows it already just sent 86 and won't send it again. I send what I get and don't worry about sending every increment.

  Thank you Vining for the comprehensive response. I only wish it made sense to my feeble mind I understand now about the round off and no need to track feedback to the decimal level (especially within a bargraph). do you know of a simplistic command that would send the variable text to the bargraph in a way that the bargraph would understand it? The denon FB seems to report back in a percentage of volume, not in a db level, so there's no need to do any math functions either, just send the value (ie 56) to the bargraph level.

  If you want to update the bargraph, simply do a send_level to it. There is no need to send variable text to a bargraph unless you want it to display text along with the bargraph level.
  
  send_level dvUI, 1, 50

  Thank you Paul for the input. I'm trying to send this level to the UI
  
  SEND_LEVEL dvDenon4308CITp,1,sPARSE1
  
  and I get the below error.
  
  ERROR: C10504: [<expr2> of SEND_LEVEL <ref><expr1><expr2>] is not compatible with a [DOUBLE] value
  
  as an FYI, sParse1 should be in an integer state based on my ATOI command.

  sParse1 must be a double so you could change that to an integer or type_cast(sParse1) in your send_level.
