How do I make a batch file launch a certain part of another batch file

I'm making a .bat game and I'm putting in save files but I'm not sure how
to, what I want it to do basically is run a batch file, "Warrior", then go
to a certain part of the code-:Fight_1. I've looked everywhere but can't
find anything. I don't need all the code, I know how to start batch files
and that and I know the call command I just don't know how to call a
certain part of a batch file. Any help appreciated, thanks!
