Hi,
I think, I've got an easy problem.. but can't solve it

I want to do a simple thing:

File 1:
"one.bat":

@echo off
echo One 
Two.bat
-------<here i="" want="" to="" get="" returned="" value...="">-------
echo The End
pause</here>

File 2:
"Two.bat":

@echo off
echo Two 
-------<here i="" want="" to="" return="" value="">-------
</here>

I tired:
EXIT /B 23 - and doesn't work..

Use new batch feature instead:

call:proc parameter
goto:eof

:proc
    echo %1
goto:eof

The line "goto:oef" in proc actually does not go to the end of file but performs a return. The value of parameter is obtained inside proc as %1.

Solution 1

Been a while since I played with this...

one.Bat:

@echo off
echo one
call two.bat
if %errorlevel%==23 goto twentythree
echo unknown errolevel
goto end
:twentythree
echo Success!
:end

two.Bat:

@echo OFF
echo two
exit /B 23

If you just execute two.bat from within one.bat, then it will return to CMD when two exits, not to the same plave in one.bat - you need to use CALL two.bat

Griff, a 5 for your answer. Just in case: do you know batch's procedures and call? They are available since NT (I think), much more robust way to work. Even in batch goto is unwanted! Please see my Answer for detail.

Hi SA: yes I was aware of them! Nasty kludge in my opinion, could have been a lot better but that would have upset the batch purists at the time I think.
Wouldn't have solved the OP's problem, but they are a valid (if badly implemented) way to do things! 5 :laugh:

Thank you. Of course it is nasty, but better than nothing. I say, the benefits of batch file starts from the fact they are always available, do not require any installations. Those benefits and right after :-)
