Running out of memory when using many if statements

UKHeliBob:
I was think more of each letter being declared like this

char letter_a[] =

{
  0b00000000,
  0b00111100,
  0b01000010,
  0b01000010,
  0b01000010,
  0b01111110,
  0b01000010,
  0b01000010
}



8 bytes per letter instead of 64 bytes per letter. 

Combine this with using the ASCII value of the letter as an index to a 2 dimensional array of letters defined as above and the code would be vastly reduced in size.

So currently I've done

char letter_a[8]={   0b00000000,
                     0b00111100,
                     0b01000010,
                     0b01000010,
                     0b01000010,
                     0b01111110,
                     0b01000010,
                     0b01000010 };

char letter_b[8]={   0b00000000,
                     0b01111100,
                     0b01000010,
                     0b01000010,
                     0b01111100,
                     0b01000010,
                     0b01000010,
                     0b01111100 };

char *(ascii_letters_symbols)[256];

ascii_letters_symbols['a']=letter_a;

ascii_letters_symbols['b']=letter_b;

this->copy_letter(ascii_letters_symbols[letter_to_get]);

it did reduced the momery usage (from 90 to 51) so is that good or I need to tweak it more ?
