Fill flash with MZ-6

[Simon King]

Hi All,
It may seem like a silly question, but can the MZ-6/ZX-L do daylight fill
flash with its built in flash? If so, how?
I almost always use an external flash and so have only just thought of this
after owning the camera for over a year.
The instructions are, as usual, pretty useless.
Cheers,
Simon
