Hi Guys,
what is the output of the below code. Please explan briefly.
Code:
CALL REVERSEIT('PL/I');
(SUBSCRIPTRANGE,SIZE,STRINGSIZE);
 REVRESEIT:[b] PROC(31);[/b]
DCL (I,J) BIN FIXED(31);
DCL (S,T) CHAR(100) VARYING;
 T=S;
 J=0;
 DO I = LENGTH(S) TO 1;
       J = J + 1;
      SUBSTR(T,J,1) = SUBSTR(S,I,1);
 END;
PUT(T);
END;

Why don't you try it and see? Did you mean to have spelt REVRESEIT in line 3?

Line 3: REVERSEIT OR REVRESEIT ??

In the DO loop, seems like you need step -1

rest its fine, i think you would get the reversed string...
