C1000 channel or function not found

[Gorkhali]

My data format is: 
T, 2021,04,02,15,03,23\013

 I can see the data comming inthe comm monitor but I am getting error:  C1000 Channel or function not found: Line 7 

The code I have written to parse this data is:

global String datain

device.Neph.Purge()

While(1)
 
try
   
datain = device.Neph.ReadUntil(13)

switch
   case(left(datain,1) == "T")

      Yr.AddValue(StrToDouble(Parse(datain,1,",")))
      MM.AddValue(StrToDouble(Parse(datain,2,",")))
      DD.AddValue(StrToDouble(Parse(datain,3,",")))
     
      HH.AddValue(StrToDouble(Parse(datain,4,",")))
      MN.AddValue(StrToDouble(Parse(datain,5,",")))
      SS.AddValue(StrToDouble(Parse(datain,6,",")))
     
     
    endcase
   
    catch()
  
    endcatch
   
   
     

EndWhile

What could be the possible error?

Thanks!

I am assuming line 7 is the case()?  I'm actually surprised you get any error since you have a try/catch() with no error indication.  You should almost always put a:

? strLastError

inside your catch() so you know when there is some issue.

I would add a ? datain after the readuntil(), or just add a breakpoint and look at the data.  I don't see anything else really wrong.
