Answer / venkatesh.layam
when ever compiling time only inputbuffer will be created
while data set creation generally 3 steps been occureed
1.inputbuffer
2.pdv.
3.discription poortion
for external file:
when ever we import the external file that time input
buffer will be created.it happends in compilation phase
in the execution process the the pdv will be created
while execution 2 types of automatic variable will be
created.
_N_ :how many times datastep has been executed
_error_=by default the erroe=0 if have any errors more than
one it displays 1
data discriptior portion:in the data set column header
called data portion
and values portions called discription portion
using datalines:
when ever you use dataline for compilation and execution
directly pdv will be created but input buffer wil not be
created because only expternal data inputbuffer will be
created.

Answer / ch .sumalatha
when the sas dataset read pdv will create.input buffer
creates only at the time of reading raw datafile.at the
time of creation of pdv --data portion ,and discripter
portion created.at this time data will read and start the
iteration of the data step .at the same time _n _ and
_error_ are created.

Answer / madhu
At compile time it creates input buffer,program data vector
and discription portion.
Input buffer is the temporary storage of memory with
variable length.
Pdv is storages lists of system defined var's and user
defined var's.
Discription portion contains details like when data set is
created, date , time , no of var's and no of obs etc.
