"ln -s" command to selected files

Hello!

Is it possible to do such a command:
Select needed files in the current directory and create symlinks for them with names the same as file names and extension - the last symbol = '0'.

For instance:
I mark following files

kjdj.doc
kdlkf.txt

Then I launch the magic command and in current directory I will have more two files:

kjdj.do0
kdlkf.tx0

which are symlinks to the first two files.

Thank you in advance.

The "magic" custom command would be:
Make sure you use right quotes. There are back-quotes around the "echo '!' | sed 's/.$/0/'"

Probably there is much better/simpler way how to achive the same results, but I'm not an expert in unix shell.

Thanks, but this command don't work with long file names with spaces.
Following command works fine:

ln -s '!' "`echo '!' | sed 's/.$/0/'`"

Just for somebody who needs this.
