what mean of this code ?

[hasula]

i found it in template section, can anyone tell me what is it ?

if ((element>='a')&&(element<='z'))
      element+='A'-'a';//----------what is this mean ?
      return element;

'A' equals to the number 65 (ASCII-Code) and 'a' -> 97

so line 2 says element+=65-97; -> element+=-32; -> element-=32;

which effectively means 'a' turns to 'A', 'b' -> 'B'. In other words to upper case.
