<blockquote>however it seems kind of useless as I am never informed as to which line of code the value for MyCoords[2].PathInitial &nbsp;changes.</blockquote>You can open more than one Watch window, and observe more than one variable in a Watch window. During debugging, you can set a breakpoint on the MyCoords[2].PathInitial&nbsp;(all the declared section)&nbsp;by clicking in the left margin, selecting Debug &gt; Toggle Breakpoint, or pressing F9. Start debugging by selecting the green Start arrow or&nbsp;Debug &gt;&nbsp;Start Debugging, or press&nbsp;F5. Execution pauses at the breakpoint. Open a&nbsp;Watch window by selecting&nbsp;Debug &gt;&nbsp;Windows &gt;&nbsp;Watch &gt;&nbsp;Watch 1, or pressing&nbsp;Ctrl+Alt+W &gt;&nbsp;1. You can open additional Watch windows by selecting windows&nbsp;2,&nbsp;3, or&nbsp;4. Continue debugging by selecting Debug &gt;&nbsp;Step Into or pressing&nbsp;F11 as needed to advance. The variable values in the&nbsp;Watch window change as you iterate through the for loop. In this case, you should able to find out which line of code the value for MyCoords[2].PathInitial &nbsp;changes. <h2>For more information, you can read this guideline ~ Watch variables with Watch windows and QuickWatch:</h2><a href="https://docs.microsoft.com/en-us/visualstudio/debugger/watch-and-quickwatch-windows?view=vs-2019" rel="ugc">https://docs.microsoft.com/en-us/visualstudio/debugger/watch-and-quickwatch-windows?view=vs-2019</a>

Thanks David. What I need to do is to track every occurrence of where the particular variable in question changes in value. If the value changes in 50 different locations, that is just too many break points to stop at. What would be nice is some type of debugging feature where I am given the line number where the variable value changes, and what the changed value is.

In Visual Studio I have a class variable (It is named : MyCoords[2].PathInitial) In my large application I need to find out when the value for MyCoords[2].PathInitial &nbsp;changes. When it does change I would like for my application to alert me somehow on the line where the change occurs, or to temporarily halt execution at the line where it has changed. Is that possible? I added a "Watch" on the variable, however it seems kind of useless as I am never informed as to which line of code the value for MyCoords[2].PathInitial &nbsp;changes.
