Homework?
You can get what i think you want by modifying the input-statement:
data a;
input letter $1. @@;
if missing(letter) then do;
input;
delete;
end;
cards;
Software
;
Is the output a data set, an external text file or what?
You can loop over a character value with something like:
do i= 1 to length(variable);
letter = substr(variable,i,1);
/* something likely goes here but without knowing the target what is not known*/
end;
