I have modified the scripts following Mortens advice. I also hardwired 
the mol-name 'current' to the working molecule. This is done to comply 
with the nomenclature of the pdb-read command, where you distinct 
between ca trace and all atom objects.
I have also added a 'mol current' command in the @yes script, this 
ensures that you will not accidentally overwrite you .undo.pdb files 
with another molecule.
Thus, @yes and @undo will only work on mol 'current'. If you work on 
several pdbs in the same o file you can make separate scripts for each 
ex. @yes1 and @yes2 for mol1 and mol2.

Enjoy!

P.S. please report any bugs directly to me.
