There were 2 function's called something like convert2Upper and Convert2lower (Don't remember the exact names) in Java that took a string broke it into characters and for each char did the following:<p>If (InputStr[$i] == 'a') InputStr[$i] = 'A';
If (InputStr[$i] == 'b') InputStr[$i] = 'B';
..

If (InputStr[$i] == 'z') InputStr[$i] = 'Z';<p>Written by someone with over 5 years 'experience'.<p>- Suramya
