Something like a function/method in batch files?

Question

is there anything that mimicks a method like one knows it from Java, C# etc.? I have 5 lines of commands in a batch file, those 5 lines are used at more than one place inside the batch file. I can't use a goto, because depending on the errorlevel created by those 5 lines I have different actions that follow. I tried putting my 5 lines inside a batch file 5lines.bat, but the original batch file original.bat only calls 5lines.bat and doesn't execute the commands after the call to 5lines.bat ): That's how my original.bat looks like:

5lines.bat echo this gets never called, how to make sure this gets called? 

There's no exit or something like this in 5lines.bat! How can I make sure the line after 5lines.bat gets called?

Answer 1

You could use the call command :

call:myDosFunc 

And then define the function this way :

:myDosFunc    - here starts the function echo.  here the myDosFunc function is executing a group of commands echo.  it could do a lot of things goto:eof
