INPUT s ;
s2=input(s,3.0);
DATALINES;

Line 2 of your code: Input s ; Makes s a numeric variable.

Try on line 3 s2 = put(s,3.0); * converts s (numeric) to a character variable s2

Jim identified the right issue. To make S a character variable, you could try:

input s $;

Then just as a learning experience, I would suggest you add to the program and also test:

s3 = input(s, 3.1);

Because you are referencing a numeric variable where SAS expects a character value it is automatically converting the number into a character string for you. It will use the BEST12. format to do this. So your when you read only the first three characters using 3.0 informat your will be reading only the leading spaces of the right aligned 12 character values.
