I am writing a PL/SQL procedure that uses the following
File Ouput command. This works fine except when the
variable v_bcallno is NULL. In this case I would want 20 blank characters output but instead ORACLE moves the values for v_dtout and v_dtdue over to the left, effectively ignoring v_bcallno. Is there a way to get 20 blanks printed out in this case for v_bcallno?

UTL_FILE.PUTF (v_circborr_fh,'%s %s %s %s %s\n',

For RPAD, the variable can not be null:
SQL> set null *
SQL> select length(rpad(null,20)) from dual;


since the variable is sometimes null, then you can use NVL:
SQL> select length(rpad(nvl(null,' '),20)) from dual;
