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
