yes, You are correct.how to change my Var name   

[Shmuel]

You probably got variables name as var1-var8 using proc import,

because your data does not include first row with colomn labels.

You can rename variables either in the out clause of proc import, as:

        out=contest(rename=(var1=FName var2=LName var3=age ...etc. ...))

or, alternativly, use as second step:

proc datasets lib=<libarary holding the dataset>;

        modify contest;

        rename var1=FName var2=LName var3=age ...etc ...;

run; quit;

sir!!! thank you so much i got the output.Just one thing need to clear, shall i specify my own length for the each variables?? if possible how can i make please give me as solution.

[Shmuel]

Renaming the variable name does not change its length. 
You may select specific character variables, only if you find it preferable, and redefine their length.

It is not a must.

You can't change the length in a PROC DATASETS only rename. You can use a data step to do both.

If you've already assigned a length and are just renaming the variables a new length won't change the variables value.
