What exactly does "...to continually track the value of..." really mean?
There are two main options for finding what value a variable has:
- print it (to screen).
- use the debugging tools.
It does not make much sense to track variable values in real time, as most functions and operations will be too fast for a human to follow them. So presumably "tracking" means during debugging... in which case these steps will lets you follow any variable that you wish to:
- set a break-point on the line after where the variable first appears.
- run the function.
- view the variable in the workspace, or open it in the variable viewer.
- step through the function using the F10 button.
Debugging gives access to that local workspace, and lets you observe the value by using the standard variable viewing tools, so you can track it easily. Depending on what you mean by "tracking".
