set myfile=D:\\sample.txt

F

You can set a variable, meaning that the complete loop should be aborted and use it like this:

:fail1
echo "Step in fail1"
pause
set exit=1

And you'd change the loop like this:

FOR /F "tokens=1,2 delims=," %%i in (%myfile%) do (
  if defined exit (
    exit /b 9993
  ) else (
    call :process "%%i"
  )
)

(broken into multiple lines for readability).

Since you are just calling a subroutine from the for loop there is no way for this subroutine to exit the loop directly. Hence the workaround with a variable.
