Batch-program launchs with 1 parameter (full path to file)

program.cmd "C:\Path\To\File\Filename.txt"

Now, this program consists of 1 command:

echo %1

And it just prints an argument: C:\Path\To\File\Filename.txt for the upper example.

But I want it to print an argument (full path) with another extension, e.g. .exe. For the upper example, I want it to print C:\Path\To\File\Filename.exe.

How to make it do that?

This answer works, but it's not particularly descriptive. Use of the tilde magic variables would be echo %dpn1.ext you could also do echo %dpn1.%2 and then use changeext.bat foo.txt bar and have the output see: for magic variable references. – Tyler Apr 17 '10 at 23:48

In your program.cmd, you can just write commands as you would normally use them at the command prompt.
