  Hi Ahson,

  There are no built-in Mu functions for this.  But here are simple (ASCII) implementations in Mu:

      function: toLower (string mixed)
      {
          let ret = "",
              diff = 'a' - 'A';
  
          for (int i = 0; i < mixed.size(); ++i)
          {
              let c = mixed[i];
              ret += if (c >= 'A' && c <= 'Z') then (c + diff) else c;
          }
  
          return ret;
      }
  
      function: toUpper (string mixed)
      {
          let ret = "",
              diff = 'a' - 'A';
  
          for (int i = 0; i < mixed.size(); ++i)
          {
              let c = mixed[i];
              ret += if (c >= 'a' && c <= 'z') then (c - diff) else c;
          }
  
          return ret;
      }
  

   

  Hope that helps,
