Subroutines (common code)

The following is a common way of having some common code (parameters are passed as environment variables):

...
set ReturnAddress=Return1
goto SomeSubroutine
:Return1
set ReturnAddress=Return2
goto SomeSubroutine
:Return2
...
goto :EOF

::::::::::::::::::::::::::
:SomeSubroutine
::::::::::::::::::::::::::
    echo *** In Subroutine ***
    goto %ReturnAddress%

A newer method to do the same thing is:

...
call :SomeSubroutine
call :SomeSubroutine
...
goto :EOF

::::::::::::::::::::::::::
:SomeSubroutine
::::::::::::::::::::::::::
    echo *** In Subroutine ***
    goto :EOF
