Obfuscating a file name

It is easily possible to obfuscate a file name by pressing <Ctrl-I> at some positions in the file name while issuing a command like 'SAVE DUMMYFILE' if you do it like this:

• 'SAVE DUMMY<Ctrl-I>FILE'

If you now try to load the file with 'LOAD DUMMYFILE' you will get a 'File not found'-Error but the CATALOG-display looks all normal! 

But beware not to forget, at which position(s) you typed the <Ctrl-I>-character if you ever want to load that file again!
