create a data set with data entry

[Ronein]

Hello

I create a data set but the  column area has no values in the data set that was created?

What is wrong?

data tbl1;
infile datalines dlm='|';
length name $10 subject $20 score 8 area $10;
input name subject score;
datalines;

Guess what is missing in this statement:

input name subject score;

@Ronein;

As @Kurt_Bremser said, you have forgotten AREA in the INPUT statement. 

But if you coded it as an all-inclusive list (_ALL_), you wouldn't have:

data tbl1 ;                                           
  informat name $10. subject $20. score 8. area $10. ;
  input (_all_) (:) ;                                 
  cards ;

run ;                                                 

Incidentally, you need neither the delimiter nor the INFILE statement with your input since you have no intervening blanks in your raw data. Plus, the proper instrument for reading raw data is INFORMAT rather than LENGTH. In your simple case the latter works, but if you had something more elaborate to read (date or datetime, say) it wouldn't. 

Kind regards
