In the following example echo on will take effect after the end of the brackets context is reached:
@echo off
(
echo on
echo ##

Anonymous functions technique uses the fact that CALL command uses internally GOTO when subroutine is called and abusing help message printing with variable double expansion:

Lets have the following file called library.cmd :
@echo off
echo -/-/- Batch Functions Library -/-/-
:function1
echo argument1 - %1
goto :eof
To execute only the :function1 without the code of the rest of the file you should put a label :function1 in the caller bat and use it lik...
