vector analysis and V9

I note that none of my 8.04 Vector Analysis works.....previously  I 
would load the program then, example,  SetCoordinates[Cartesian[x,y,z]] 
and then I could use Div, Curl, etc....

Now I notice I have to write, for example,   Div[vector,{x,y,z}]....In 
all my previous code every Vector Operation comes back with incomplete 
Command requiring , in this case, {x,y,z} added to the command.....Is 
this for real?....I have to specify the coordinate system variables 
every single time I do a Vector Operation????

Or, hopefully, have I missed something here?......Let me add....I notice 
that I can still load the 8.04 Vector Analysis and then the commands 
work as before....

thanks....Jerry Blimbaum
