Answer / sattwik panda

x=substr(name,1,2) will return first two character of a string whereas substr(name,1,2)='x' will replace first two character by 'x'.
Please try using the code below to get an idea.
data test;
name="Sattwik";
x=substr(name,1,2);
substr(name,1,2)='x';
run;

x will have the first two characters of name:'Sa'.
substr(name,1,2)='x' will replace first two characters of "Sattwik". So, now the name will contain "xttwik".

Answer / pratik

I agree with the first answer just a change is .it will be
"x ttwik" rather than "xttwik" as the replacement happens from the first loacation not as a whole.

Answer / oanhntt

x=substr(name,1,2) means you assign x value equal to the
first 2 characters of variable "name" while
substr(name,1,2)='x' just compare these fist 2 characters to
value 'x', so this seem useless without condition syntax
(correct one should be: if substr(name,1,2)='x' then /*do
some thing*/;).
