Changing the dir of a patch

[Linium]

Hello,

I would like to know if there is a way to change the directory wich is
displayed in the title bar after the name of a patch.

There are some opcodes that take this information for disk output and
sometimes you don't want that the datas go to this dir.

On another hand, how to retrieve this information ? I would like to 
automaticly get the dir of a main patch to send it to my various saving
mechanisms.

Best regards,

Linium
