It is true to use KEEP option on a dataset to only select
few variables from 100 variables.
We can use KEEP option either on set statement or data
step statement. If we use on SET statement then only the
five variables are created on pdv and only these variables
are sent to the output dataset. If we use KEEP option on
data step statement then all the variables are copied into
pdv and after any maniuplation only the selected variables
on data step statement are processed and sent to output
dataset.
data abc;
set xyz (keep= ab cd ef gh);
run;
data abc(keep= ab cd ef gh ij);
set xyz;
ij=ab+jk;
run;

If ur reading data from any dataset we will use keep option
like set data1(keep = 5 variables);,If ur using in any
procedure just with var statement.If u want to display to
have output with only 5variables out of 100 just use keep
option with data statement.

Answer / chiranjeevi
My guess is using data set option i.e keep
it is used for it decides the no. of variable should remain
with in the dataset
keep<variable list>
2)var statement
it is a keyword or statement used to specify the analysis
variables.The analysis variables are those,which is required
to be restructured.
