retrive case sencitive data

[BrahmanandaRao]

Hi Guys;

Here I am trying to get upcase data and low case data 

data low_upper;
input name  $  city $ 15.;
cards;
ravi mumbai
SIRISHA HYDEABAD
vinay delhi
GANESH BANGALURU
;
run;

data low;
set low_upper;
if name upcase(name) then output;
run;

What does this log tell you:

 83         data low;
 84         set low_upper;
 85         if name upcase(name) then output;
                    ______
                    22
 ERROR 22-322: Syntaxfehler, erwartet wird eines der folgenden: !, !!, &, (, *, **, +, -, /, ;, <, <=, <>, =, >, ><, >=, AND, EQ, 
               GE, GT, LE, LT, MAX, MIN, NE, NG, NL, OR, [, ^=, {, |, ||, ~=.  
 
 86         run;

and what would you do to fix it?

After ~400 posts here, this is trivial for you to fix.
