[Solved]expected identifier before numeric constant when instantiating object...

Move the table outside, like this, then it compiles:

//Set up the ASCII tables
byte nokia5110::ASCII[][5] = {
  {0x00, 0x00, 0x00, 0x00, 0x00} // 20  
 ,{0x00, 0x00, 0x5f, 0x00, 0x00} // 21 !
... blah blah
 ,{0x10, 0x08, 0x08, 0x10, 0x08} // 7e ←
 ,{0x00, 0x06, 0x09, 0x09, 0x06} // 7f →
 };
 
nokia5110::nokia5110(int SCE, int RESET, int DC, int SDIN, int SCLK)
{
  //Set up the pins
  pinMode(SCE,   OUTPUT);
  pinMode(RESET, OUTPUT);
...
