Datassette
FUes
Now
that
you have
had
a chance
to
look
at
files in a general way, you
can apply them
to
reading from and writing to the Datassette. The VIC
Datassette is the default external storage device.
That
means
that
if you
don't specify which device you are writing to, the information will go to the
Datassette. .
