In a previous message, Pete is having problems with his loops for processing
strings.   I suggest:
 PROCEDURE P(VAR S : ARRAY OF CHAR);
 VAR k,n   : CARDINAL;
 BEGIN
    n := Length(S);
    FOR k := 1 TO n DO
      process(S[k-1]);
    END;
If you don't like the "k-1" then the other alternative is:
 PROCEDURE P(VAR S : ARRAY OF CHAR);
 VAR k,n   : CARDINAL;
 BEGIN
    IF n>0 THEN
       FOR k := 0 TO n-1 DO
         process(S[k]);
       END
    END;
