proc format ;
invalue age 11=100 12=200 13=300 14=400 15=500 16=600 ;
run;

data s ;
set sashelp.class ;
new_age=input(age,age.) ;
run;

when i run above program it gives data but show not log window like see below photo

The input()function expects a string as its first argument, so SAS needs to convert the numeric age to character first.

To avoid the message, add a put() inside the input() to explicitly convert age.

If you ever read the documentation for the INPUT function you would know that the first parameter is expected to be character values.

Since you have used INPUT with a numeric variable AGE in the position where it expects character values then SAS tries to help by converting the numeric variable to character to do what you attempt. And then it places the note in the LOG to tell you that may have done something you did not expect with the implication that the result might not quite be what you expect.

Formats are for converting values to text and informats for converting text to values.

You use formats with PUT statement and PUT() function.

You use informats with INPUT statement and INPUT() function.

You need to either define a FORMAT instead of INFORMAT, or use the INPUT() instead of the PUT() function.
