dos batch string manipulation

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

1@echo off
2set wpath=%1
3@echo.%wpath%
4set newpath=%wpath:~0,-4%
5@echo.%newpath%

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

1script.bat whatever/test.txt
2whatever/test.txt
3whatever/test

But I'm getting

1script.bat whatever/test.txt
2whatever/test.txt
3<emptyline>

I'm using DOSBox version 0.74 and this as a reference

Does that stuff work in real DOS? DOSBox's shell emulates MSDOS 5/6 (and only to some extent), not the Windows Command Shell.

Have no idea, I haven't used anything but linux for the past decade. Works on XP's cmd

Any other suggestion?

well, that reference site calls itself DOS Tips yet says it's "for Windows7, VISTA ,XP, NT, Server 2000, Server 2003, Server 2008".

[cue Family Guy style showtune parody - "the Windows command prompt isn't DOS, isn't DOS, isn't DOS"]

Do you need the extension-less pathname as a variable? or just want to echo it out?

Just use 4DOS, it has a number of advanced string manipulation routines.

It works only in the Windows command-shell, because it's relying on an extension that was added in Windows XP.
