At compile time when a SAS data set is read, what items are created?..

Answer / vemula

compilation time 3 items were create
1.input buffer
2.pdv
3.descriptor portion.

during compilations first it checks the syntax
then it assigns the datatype and informat
then it translates the sas code to standard machine code

1.input buffer: It is a logical area where sas reads each
record at a time when input statement is executed.
2. pdv: it is logical area in memory into which
SAS builds sas dataset one record at atime
3. descriptor protion: it contains the information about
dataset attributes and variable attributes

dataset attributes include when it was created etc
var attrb such as datatype format informat length etc.

Answer / pratik singh jageera

An input buffer is only created when data is read from external files/datalines not in case of reading data step.So the appropriate answer will be just PDV and Dataset Descriptor.
