Want to understand how some VBA code works

Hello Forum,

I am a new user, with limited to no knowledge of VBA. Due to circumstances, I have a couple of reports with a few lines of VBA codes whose purpose I want to understand. What would be the best resource to leverage in order to accomplish this? Again, I have very limited VBA knowledge, but am willing to read or research. However, I ask here first as a way to be pointed in the right direction and for guidance.

Thank you to all respondents.
