Answer Posted / latha reddy
PDV: it is a logical memory area.
and pdv brings the observations at a time from input buffer
and checks the errors.
PDV contains 2 automatic variables _n_ & _error_ ,these
checks the erros in observations.
_n_ : indicates the no of obs.
_error_: 1 if error occured
0 if no error
After that it assigns the datavalues to appropriate
variable and build a sas dataset.
