Using CALL for labels in a batch script

Why not just run it and see for yourself? I saved your script to a batch file called foo.bat, and I changed the Your mom goes to college. to have an echo in front.

C:\temp>foo

C:\temp>ECHO It's for my college fund.
It's for my college fund.

C:\temp>CALL :OMGSUB

C:\temp>echo Your mom goes to college.
Your mom goes to college.

C:\temp>GOTO:eof

C:\temp>ECHO *runs away and cries like a little girl*
*runs away and cries like a little girl*

C:\temp>echo Your mom goes to college.
Your mom goes to college.

C:\temp>GOTO:eof

C:\temp>

So it's easy to see that after the OMGSUB is called, it

1. Goes to the end of file.
2. Then it returns to the line right afer the CALL :OMGSUB and echos the "runs away" line
3. Then it echos the Your Mom line again
4. Then it goes to end of file and terminates
5. The line echo *picks up jewewlry box* never gets reached.
