Batch: how to pass parameters to function inside a batch script?

Question

I have a sample batch script:

@echo off

:installed
    echo "checking %1"
    goto :eof

call:installed "aaa"

And when I execute this script, I get the "checking " output, as if there were no arguments passed.

I'm on Windows 8.1

You just need to rearrange your program a bit to manipulate the order of execution.

@echo off
call: installed "aaa"
goto :eof

:installed
    echo "checking %~1"
    goto :eof

parse your file manually:

@echo off is executed.

:installed the label is ignored

echo "checking %1" is executed with empty %1

goto :eof the batchfile terminates.

The rest is never executed.

Just change the order of execution:

@echo off
call:installed "aaa" 
goto :eof

:installed
    echo "checking %1"
    goto :eof
