Complete a string with "@" depending on it length

[#1]

Hi, I'm trying to do something like this to complete some string variable with "@" depending on it length:

x is a number variable that receives the length

y is a string with multiple length

z is the destination variable

x = length(y)

if x < 50 then

   a || 50 - x  /* at this point I'm trying to put some number of repeated "@" to complete a length of 50 */

else

   substr(a,1,50) /* if length is greater then 50, I just cut it using substr */

end if

Regards from Brazil

You could try:

Data A;
  Input y $20.;
  Datalines;
SDFED
GDDE CDEX
DFDXCE
DD
;
Run;

%Let x=40;
Data B;
  Set A;
  z=Repeat('@',&x.);
  Substr(z,1,Length(y))=y;
Run;
