what is pdv? how it is related to input buffer in sas?
Answer Posted / nanda katepalli
PDV is the program Data Vector. It takes each observation at
a time and allocates the length given in the input
statement.The allocation of spaces is done in the
compliation phase and the variables goes in it at the
execution phase.
Example:Builder builds the house but it is used by the people.
It has 2 variables by default which are _n_ and _error_.
_n_ gives us the observation number.
_error_ if their is no error then it is 0 or else it shows 1
even though we have 'n' no.of errors.
And then it creates 'n' no.of variables specified in the
data statement.
Input buffer is only needed for non sas files to
read the raw data and store in it. Where as, sas files do
not need the input buffer.
Example: Converting an Excel file into a sas file i.e while
converting it needs some space for storage.
