How to find the source line for a 'ans' output displayed in command window

I am running a code in a function, at the end of the code, an output is getting generated as junk. So could you please help me out in finding source line for the data. The data is being generated as 'ans' without any variable. I have tried echo and debugging the code, but of no use. Kindly resolve.

The Code Analyzer should provide a message on this. Open the file and on the right hand side you will likely see an orange dash on the offending line.
