The exitcode returned is whatever value the script returned. Which may or may not be relevant to the reason why it exited.

For example, the code could be doing: 

## 42 is such a crass true value
exit(+1-2+3-4+5-6+7-8+9-10+11-12+13-14+15-16+17-18+19-20+21-22+23-24+2
+5);

The point is, it is the value returned by the program or script you are running, which may or may not relate to windows system error codes.

You need to look inside that script to understand what that number means.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
