There's one use for it - data obfuscation. Create a data set with a
duplicate variable, and put the info you don't want ordinary users to be
able to browse into the second variable.

Hi friends,
Obviously it is not SI's intention to allow duplicate variable names.
Where it still is possible, merely seems to be an accident, a bug, not
a feature.
I would not count on it and never want to think of such duplicates.
You do not need it. If importing strange data with duplicate names then
rename.
Regards - Jim.

Blimey, didn't know it was possible. That's going into my handy links
for future reference (just in case).
Cheers, Andy

I agree that you probably don't want duplicate a variable name in a
data
set, but it is possible. One way to get one is explained in
<http://support.sas.com/techsup/unotes/SN/003/003951.html>; I've
encountered other ways, but each new release of SAS makes it more
difficult.
Once you have such a data set, it's difficult to get the value of the
second variable, but some procs allow it, and you could probably get
to
it in a data step using the data set information functions, or maybe
using an array.

Although it's impossible to have two variables with the same in a
dataset, for whatever reason you'd want to do this (and I can't think
of
a single one) you could have the variables with the same label for
printed output.
Hope this helps,
Andy
i.e.
data test;
length x1 8.
x2 8.
x3 8.;
label x1="x1"
x2="x2"
x3="x2";
input x1 x2 x3;
datalines;
1 2 3
;
run;
Proc print data=test label;
run;
gives
The SAS System
Obs x1 x2 x2
1 1 2 3
Hope this helps,
Andy

Vickey,
Why would you want to do this? Secondly, how would you tell sas to do
something to one x2 and not the second x2 (or vice versa)?

Subject: Re: May be you've had this problem
I tried the folowing code and every thing was fine...
data test;
input x1 x2 x3;
datalines;
1 2 3
;
run;
But when i assign the same variable name to 2 variables i mean my
input satament is like
input x1 x2 x2;
then it is considering the last variable and not the second one.
CAN ANY ONE TELL ME THAT HOW TO SOLVE THIS PROBLEM...I WANNA MY DATA
SET HAVING THE SAME VARIABLE NAME 2 TIMES.
thanx in advance
vickey
