it has to do with various writing styles avail for the programmer. or alt ways of calling functions.
i.e. I hope I am explaining myself ok here.

=myfunction(1,2) && whatever is returned from that myfunction() is tossed away.
myfunction("1","2") && implys there is nothing to be returned, from the Function.
and
myvar=myfunction(1,2)

stores whats returned from myfunction as a memvar named myvar.
