char type can store numeric values. You can write:

     unsigned char myBlock = 42;

you can convert an integer to char if you like.

    int myInt=42;
    unsigned char myblock;
    myblock = char(myInt);

Note that on x86 architectues char type size is 8 bits. Therefore the
maximum value it can hold is 255. If you assign a larger integer to
it, the higher bits will be lost. For example:

  int myInt=256;
  unsigned char myBlock;
  myBlock = char(myInt);
  cout << int(myBlock) << endl;

prints zero.
