Joey's answer is great. I have used it with success. I discovered that you don't have to exit the script though. You can use goto :SomeLabel, where :SomeLabel is a label outside of the loop.

FOR /F "tokens=1,2 delims=," %%i in (%myfile%) do (
  if defined exit goto :ParseError
  call :process "%%i"
)

@echo SUCCESS: %myfile%
goto :RestOfScript

:ParseError
@echo FAILURE: cannot parse %myfile%
@echo Using defaults...

:RestOfScript
...
