I need a help because, I don't know how to convert the variable with especial character to be convert to without especial character .

To use such a variable you have to set VALIDVARNAME option to ANY.

Then you can use RENAME statement to change the name.

options validvarname=any;
DATA B_LDIG;
      SET &LDIG.;
      rename 'DÍGITO'N = DIGITO;
RUN;

How did the variable get that name to begin with?  Perhaps you can fix the issue earlier in the process.
