dos batch string manipulation

[Alin Rus <netblock@xxxxxxxxx>]

Hello,

I'm trying to write some dos batch script for manipulating some paths.
I haven't done this in years so I might be rusty.

The path is relative and given from the command line as argument

@echo off
set wpath=%1
@echo.%wpath%
set newpath=%wpath:~0,-4%
@echo.%newpath%

The thing I'm trying to accomplish is to get rid of the extension

script.bat whatever/test.txt
whatever/test.txt
whatever/test

But I'm getting

script.bat whatever/test.txt
whatever/test.txt
<emptyline>


I'm using dosemu-1.4.0.1 and this [1] as a reference.
